[R] R_USER - in which file should I include it?

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:

[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:


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

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:


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?
