[R] consolidate three function into one

Hi Bert,

Thank you, yes, you are right.  I want to consolidate the three functions into one functions by adding more arguments, adding flexibility  to accommodate  the number of clusters or  the number of Kaplan Meier  curves generated in one figure.  So, I just need to define one function.

Thanks,

Ding

I have not looked at your code *at all*, so I am not sure what exactly you mean by "consolidate."
Is this what you are after?

f1 <- function(...) { code 1}
f2 <- function(...) { code 2}
f3 <- function(...) { code 3}
## can be "consolidated as":
f <- function( someargs, ...){
if( expr(someargs)) f1(...)
else if(expr2(someargs)) f2(...)
else f3(...)
}
The "..." argument to f can soak up any named additional arguments you wish to pass to f1, f2, or f3.
My apologies if this is offbase or too vague, and feel free to ignore in that case. I don't have the patience to go trough your code in detail. Others may and give you what you want.
Cheers,
Bert

HI R users,

I construct dendrogram tree and cut the tree into different clusters, then generate survival curves by the following three functions. All variables are included in an inputfile.

Can you help me to consolidate the following three function into one functions?  I thought about using if  else function, but not sure how to do it.

Thank you,

Ding

hello,
Can you please give me a hand with this problem,well i can't install these
packages:
- stats
- methods
- stats4

when i tried the following command :  *library(help = "stats") * , it gave me this output (*see picture*), so i contacted the Maintainer of the package at (*R-core at r-project.org<mailto:R-core at r-project.org> <R-core at r-project.org<mailto:R-core at r-project.org>>*) but he said that i write to the wrong place.

(i want to install those packages in order to use the "DVstats" package)

(i have the latest version of R (3.4.3 ) and Rstudio(1.2.240) )

thank you
Regards
