>From Tom:In R 2.2.0 under Windows, I want to be able to give it a filename such as "myFile.txt" without the quotes. But actually I mean: C:\Documents and Settings\Tom\My Documents\qpaper7\R Project Started 19 Dec 05\myFile.txt If I were to repeat this each time, my computer would get all bored and cranky and start to drop bits (only a joke, of course). I think I want to set the Home directory or the working directory or some directory or other to the above directory. I may or may not want to set some environmental variables. R 2.2.0; working directly from the console and copying and pasting code which I want to test into the console. Windows XP Home Edition. Administrator privileges are enabled. A curve ball: There are two accounts, "Tom" and "Jones;" the data are stored under "Tom," whereas the computation is being done under the "Jones" account. I won't bore you with the details of why I am doing this. I was able to call Sys.getenv ("R_USER") and get the home directory. I am a newbie to R and not familiar with the terminology. Tom Thomas L.

I think you want getwd() and setwd(). HTH, Simon. Thomas L Jones wrote:> >From Tom: > > In R 2.2.0 under Windows, I want to be able to give it a filename such > as "myFile.txt" without the quotes.

[R] How do I tell it which directory to use?
Tom, You can define your working directory by using: setwd("C:\Documents and Settings\Tom\My Documents\qpaper7\R Project Started 19 Dec 05") check that your file is there: list.files() and then use: source("myFile.txt") the machine should load "myFile" You can go to another directory: setwd("anotherdir") and repeat the procedure. Or even better if you define a number of directories in an external file: dir1 <- c(C:\Documents and Settings\Tom\My Documents\qpaper7\") dir2 <- c(C:\Documents and Settings\Tom\My Documents\") and after loading the file at the beginning of the sesion you can use: setwd("dir1") etc. Is it of any help to you?
