Re: [R] Setting up a .Rprofile file

[Henrik Bengtsson]

R for Windows is a bit peculiar where it locates your .Rprofile file,
or rather what it consider to be your home directory.  If you look
from within R, the file you do want to create / edit is:

> f <- normalizePath("~/.Rprofile", mustWork = FALSE)
> f
[1] "C:\\Users\\joe\\Documents\\.Rprofile"

For instance, to change what your R prompt looks you can add this from
within R as:

> cat('options(prompt = "> R ")\n', file = f, append = TRUE)

Hope this helps

No. See ?setwd . It requires a dir argument and will therefore give an
error if one is not supplied. Nothing to do with "knowing" what the
current working directory is.

No (imho, anyway). Your working directory may change over time,
depending on how you organize things of course.

Please re-read the advice you have been given as well as ?startup.

Cheers,
Bert

Re: [R] Setting up a .Rprofile file

[Bruce Ratner PhD]

Henrico:
Thanks for quick reply.
However, one last question:
If I want to change working directory, and put setwd() in the Rprofile file, 
logically R will not know where the be work directory is, correct?

So, should I install R in my preferred working directory?

Thanks again, in advance.

Re: [R] Setting up a .Rprofile file

[Jeff Newmiller]

OP is on some variant of MSWindows, which doesn't use a Bash shell, so the 
syntax of that example is a bit foreign, Enrico. 

I would say that the concept of using .Rprofile to change directories is 
ill-advised, since having ALL of your R work in one place is not sustainable. 
However you can make one or more clickable icons (shortcuts) on your desktop or 
start menu with the Startup Directory property set to the directory you want to 
work in. You can modify a shortcut made by the installer, or  hold the Alt key 
down while dragging the RGui.exe icon to some convenient place, and use the 
right-click popup menu to change Properties.

I used to create a .RData file in the directory I wanted to work in and double 
click that to get R started in that directory, but the side effects of loading 
objects into the R global environment can really confuse things and create 
puzzling behaviour if that file gets changed. These days I use RStudio and 
double click on a .Rproj (project) file to get RStudio going with the directory 
set to where that file is without mucking with the global environment.

Hm, I think I don't understand what you mean here. Where R
is installed and where it is run are (usually) not the same
places.

Let $ be a shell prompt, and let > be the R
prompt. Then:

  $ cd /tmp/
  $ R -q
  > getwd()
  [1] "/tmp"
  > q("no")
  $ cd ~/Documents/
  $ R -q
  > getwd()
  [1] "~/Documents"

Now I write into my "~./Rprofile" file:

  setwd("~/Downloads")

$ cd /tmp/
$ R -q
> getwd()
[1] "~/Downloads"


But maybe I am completely misunderstanding what you
mean

Kind regards
 Enrico
