R_USER - in which file should I include it?

Hello

Many thanks.  It works just fine.

How about the packages issue?  That is, same thing for the installation
path.

Cheers

Ed

Try adding this at the end of your etc/Rprofile.site file.  That file
should already be there so you don't have to create it,
just edit it.

cat("Hello from Rprofile.site\n")
setwd("C:/Users/eduardo/Documents")

You may need to edit it as Administrator.   You should
see the Hello message in which case you will know that the
Rprofile.site file is being run.

That should work unless Tinn-R runs R in such a way as to
ignore Rprofile.site.

Hello

I am not sure whether R starts from the same dir.  For instance:

a) if I double-click on R-2.7.2 icon and then issue the command getwd(),

the

result is:

getwd()

[1] "C:/Users/eduardo/Documents"

b) If R starts from within Tinn-R, the result is:

getwd()
[1] "C:/Program Files/R/R-2/bin"

I want that no matter which calling R method I am using if I issue the
command getwd() (first command) the result is:

"C:/Users/eduardo/Documents/R"


Moreover all new packages go to "C:/Users/eduardo/Documents/R/win-library"


Thanks

Ed

Could you explain more clearly what you mean by "the same"?
Do you mean that each time you click on R 2.7.2 icon on your
desktop that running this from the R console:

getwd()

is the same directory on each startup?  Isn't that already the case?
I don't think you need to set any environment variables at all.  If
you don't set
any environment variables then what specifically is happening that
you don't want to happen?

Hello

I am a newbie.  I had my R upgraded from 2.7.1 to 2.7.2 and in doing so I
decided to install all 2.7 versions under c:\program files\R\2.7 from now
on (2.7.1 is located under .\2.7.1)

Although I don't like the idea (I am running Vista), I have edited
etc\Renviron.site to contain:


R_USER=c:/Users/eduardo/Documents/R
R_LIBS_USER=c:/Users/eduardo/Documents/R/win-library/2.7

As far as R starting always from the same location, that is,
c:/Users/eduardo/Documents/R, etc\Renviron.site didn't help.  So I wonder
whether someone from the list could help me to:

a) force R to start always from the same location
b) force R to install all new packages in the same location


Many thanks

Ed
