[R] Rtools required

[Wang Jiefei]

I do not exactly know what is going on with your problem but it is better
to use the old-school method to install the package so that you can avoid
any problems with Rstudio.

>From your post, I guess you are using Windows, so please see this link for
how to add the Rtools and R to the environment variable PATH:

https://www.computerhope.com/issues/ch000549.htm

 Then go to the command prompt, here is how:

https://www.howtogeek.com/235101/10-ways-to-open-the-command-prompt-in-windows-10/

Type R and enter. If you can see welcome information from R, that means at
least you have correctly added R into PATH. Check whether the R version is
4.0

Type "q()" to quit R, then go to the directory where your package is. For
example, if your package is in "D:\packages\mypackage", go to
"D:\packages\".

Type "R CMD INSTALL  mypackage", replace mypackage with the true folder
name of your package.

If everything is correct, you should be able to install the package. If you
get the same error, type "echo %PATH%" and post here so we can know exactly
what is going on.

Best,
Jiefei
