I think the answer to the question is just that there isn't much demand
for them:  emacs is mainly used by Linux users these days.

But the source to the manuals is available, so presumably you could
produce these pretty easily yourself.  The R-devel versions are here:

I don't know whether the .texi files are sufficient for emacs or whether
you need to process them first; I'm not an emacs user.

Hi Akshay,

I usually use debug (a function provided by R). When you are stepping through a function your environment is the one in which function code is being executed, so you can easily see everything that is visible to the function. If you single step into a function that the first function calls then you also see everything that is available to that function. Moreover, you don't see anything that is not visible to the function you are debugging, so you can really determine what any piece of code would do if called inside the function.

Note 1: Code in R is always executed in an environment. I show in the example below that in the empty environment (the ultimate ancestor of all other environments) R can't even add. Usually the current environment (e.g. .GlobalEnv at the command line or a fresh environment created by a function call) has the right contents and the right parent to do what you expect, but in some special cases you need to understand how environments work. Even evalq & with are functions (unavailable for example in the empty environment), and the environment argument has to be evaluated in the current environment before the main expression can be evaluated in the environment that you want.


> E[1]

[[1]]

<environment: R_EmptyEnv>



> evalq(2+2, E[[1L]])

Error in 2 + 2 : could not find function "+"

> evalq(2L+2L, E[[1L]])

Error in 2L + 2L : could not find function "+"

Note 2: Besides automatically showing what a function sees, using debug (instead of hand-executing lines of code from the function) gives you the correct call stack. Suppose that you run some code at the debug command line to make a sub-sub-…-function do what you want, and you create in that environment what you hope is the correct return value. You can then use parent.frame() to put that value into the environment of the caller and run the caller's remaining code in the correct environment to see what happens. If there are no other problems then you can work your way up to top level and confirm that your patch has the right effect before you even modify the actual code of the offending function. (Saving all environments in .GlobalEnv forces R to keep them even if you quit the debugger. Combining eval & parse is sometimes more convenient than using evalq.)

Regards,
Jorgen.

Dear Jorgen,
                        regrets to reply this late....
I got into this issue because it threw an error, and it took more than 4 days to fix this. I  learnt a lot, and one things I learnt  is to debug the function, even when that is a public package function....instead of googling the error message...Any ideas on how to do this more efficiently?

THanking you,
Yours sincerely,
AKSHAY M KULKARNI

Hi Akshay,



Lexical scoping and environments are closely tied. (I think Bill even cited the documentation.) I guess it's arcane in the sense that scoping usually does what you expect, but the way that works is related to what we discussed.



What led you to discover the issue? Were you debugging the public package function because it didn't do what you expected, or were you just curious how it worked?



Regards,

Jorgen.

It may help to expand a bit on Bill Dunlap's answer. I think that library does something like this:



Create a new environment for all the package objects. This environment will not be directly visible from .GlobalEnv, and ancestor environments may not be directly visible either. It may contain functions & other objects that are not exported, and it may use objects in ancestor environments that .GlobalEnv doesn't see directly. On the other hand, functions in the package will still see external functions in the way the package author intended instead of seeing functions with the same name that are visible to .GlobalEnv.



Run the source code in the private environment (using source(local=private environment, ....)?). Most package source code just defines functions, but the source code could build other objects that the package needs for some reason, or it could use delayedAssign to build the objects lazily. By default, the environment of any function defined by the source code is the private environment, so the function has access to private objects and to anything in ancestor environments.



Create a second new environment whose parent is parent.env(.GlobalEnv). For every export, assign the corresponding object from the private environment into the corresponding name in the public environment. Note that the environment of any function is still the private environment in which it was created. (I think that a function is mostly determined by its environment, its formals, and its body. A function call creates a new environment whose parent is the environment of the function. Thus whoever wrote the function can control the search for anything that isn�t passed in or created by the function itself.)



Reset parent.env(.GlobalEnv) to be the public environment. This makes all the exported objects (usually functions) available at the command line and allows the user to see everything that was available before (usually by name only, but by scope-resolved name if necessary). As noted by Bill Dunlap and in more detail above, package functions can use functions & other objects that are not directly visible to the user. As he also showed, you can (usually) pierce the privacy as long at least one function is exported. environment(package_function) is the private environment, so you can use it to see all the private objects and everything in the ancestor environments. You can repeat the trick to see private environments of packages you didn't directly pull in. I think you can even unlock bindings and do ghastly things to the package's private environment.



Regards,

Jorgen Harmse.

Look into R's scoping rules.  E.g.,
https://urldefense.proofpoint.com/v2/url?u=https-3A__bookdown.org_rdpeng_rprogdatascience_scoping-2Drules-2Dof-2Dr.html&d=DwIGaQ&c=27AKQ-AFTMvLXtgZ7shZqsfSXu-Fwzpqk4BoASshREk&r=ug-gw1ia3rShGleyKIdg4GIXRt6aKD3u1CM4odHlsvE&m=FCARkfGgHXcSaTZN1f38_6XCbtZ-Lopl641M4MpApMJf7EuJ7y2Y4873aWz38wiY&s=Mb3F4Yi_5e0mAkovoM8_Dai8vSPPDK3hbOWblRvh4Yo&e=.

* When a function looks up a name, it looks it up in the environment in
which the function was defined.
* Functions in a package are generally defined in the package's environment
(although sometimes they are in a descendent of the parent's environment).
* When one searches an environment for a name, if it is not found in the
environment the search continues in the parent environment of that
environment, recursively until the parent environment is the empty
environment.

Note that the environment of any function is still the private environment in which it was created. (I think that a function is mostly determined by its environment, its formals, and its body. A function call creates a new environment whose parent is the environment of the function. Thus whoever wrote the function can control the search for anything that isn�t passed in or created by the function itself.)



Reset parent.env(.GlobalEnv) to be the public environment. This makes all the exported objects (usually functions) available at the command line and allows the user to see everything that was available before (usually by name only, but by scope-resolved name if necessary). As noted by Bill Dunlap and in more detail above, package functions can use functions & other objects that are not directly visible to the user. As he also showed, you can (usually) pierce the privacy as long at least one function is exported. environment(package_function) is the private environment, so you can use it to see all the private objects and everything in the ancestor environments. You can repeat the trick to see private environments of packages you didn't directly pull in. I think you can even unlock bindings and do ghastly things to the package's private environment.

Look into R's scoping rules.  E.g.,

* When a function looks up a name, it looks it up in the environment in
which the function was defined.
* Functions in a package are generally defined in the package's environment
(although sometimes they are in a descendent of the parent's environment).
* When one searches an environment for a name, if it is not found in the
environment the search continues in the parent environment of that
environment, recursively until the parent environment is the empty
environment.

But I am trying to get all the labels (the writes) : comfort, university, economic, world, ... smaller.
How could I do that ?

Many thanks.

Hello,

I'm not finding "smaller" but are you looking for


rownames(res.ca$row$coord)
rownames(res.ca$row.sup$coord)

?

Hope this helps,

Rui Barradas

If you use [Page Up]  and [Page Down]  there is no "flickering",
also using the cursor (up/down "arrows").
Still here, I would not think anything to be "wrong".
If you tell the computer to refresh a screen more quickly than
makes sense I guess you must expect what you see here.
(but yes, more modern GUIs would do 'smooth scrolling' here; I
 think that's not available for the graphapp GUI in R for Windows)

By "scrolling", what exactly do you mean?
Is it that you use your mouse "wheel"? ...  I assume "yes" in
the following, because in that case I can partly reproduce what
you describe.

At first I wrote
   I don't understand how you can "scroll down" in this plot

but now that I've guessed you mean "mouse wheel scrolling" I can
indeed see what you describe.

That you bring R to crash just by "scrolling" really seems a bad
thing and points to a bug.
OTOH, I have not been able to replicate a crash.

I don't know what mouse-wheel-scrolling should do in a graphics window
in R for Windows.
In our terminal server version of Windows,
using Rterm (via ESS = Emacs Speaks Statistics), I can indeed
see that  mouse-scrolling in a graphics window has *very funny*
/ strange effects when using the default interactive graphics
device ( .Device == "windows" ) :

Notably, after say   pairs(iris)    mouse-wheel-scrolling
"kind of" redraws some of the panel plots mostly in full size
(instead of the size they were as panels and as part of the full
"pairs" i.e., scatter plot matrix.

If instead I use RStudio and their own device "RD<something>"
mouse-wheel-scrolling has no effect, e.g., after  pairs(iris).
And "no effect" is clearly better than what we observe with the R
default device "windows" i.e., windows() in the above situation.

Hallo Sacha

AFAIK the functions in FactoMineR do not enable to manipulate label size. Plot
is performed by this part:

if (graph & (ncp > 1)) {
        print(plot(res, axes = axes))
        if (!is.null(quanti.sup))
            print(plot(res, choix = "quanti.sup", axes = axes,
                new.plot = TRUE))

and the function is not designed to accept additional parameters to manipulate
size of labels.

I struggled with it few years ago and I decided to use biplot instead as it
enables more options.

You can contact maintainers if they consider an improvement in future
versions. Probably simple ... in function definition and print(plot(res, axes
= axes, ...)) addition could do the trick, but I am not sure.

Cheers
Petr
