Rtools required

Good point, but I am bothered by the non-discrimatory warning message
to 
all package installation attempts. My students install mostly binary 
files, and I just hate to have them install Rtools. For one, they have 
not had to do so until after RStudio-1.1.463. The fact that using this 
older RStudio? can avoid the annoying warning message speaks volume.

Wouldn't packages that have to be built from source on installation
require Rtools?

Thanks to all - very helpful. I search from c:\ and now find file
.Renviron located in C:\Users\USER\Documents. That does it.

I would like to pose an additional question, since it would also

fall

under the same subject line. This is an RStudio question but since I

am

using the free version the RStudio folks would not help me.

My students simply need to install packages and are not building any
packages so they have no reason to install Rtools.

When they install (not build) packages (from CRAN or file archive)

they

received the same warning message saying

"Rtools required to build a package".

This is nonsense of course as they are, as I said, simply

installing. I

tell them to user an older RStudio version, specifically 1.1.463

that's

free of that warning. Any idea?

Dear Steven,

It's possible that Windows will hide .Renviron, but it's generally

a good idea, in my opinion, in Folder Options > View to click "Show
hidden files" and uncheck "hide extensions". Then .Renviron should show
up (once you've created it).

Best,
   John

Type
?.Renviron
?R.home
?"environment variables"

at the R prompt to get what I think should be the info you need

(or at

least useful info).

Thanks John. Where is file .Renviron located? It must be a hidden

file.

I cannot find it.

Dear Steven,

Did you follow the instruction on the Rtools webpage to add

        PATH="${RTOOLS40_HOME}\usr\bin;${PATH}"

to your .Renviron file?

I hope this helps,
    John

Dear All

I updated to R-4.0.0. and also installed the latest Rtools 4.0

(to

now the new default folder c:\rtools40). While compiling a

package

(binary) I received the follow marning message saying Rtools is
required. Any clues? Thanks.
