Dear friends,
I will be very happy if anyone tell me the way to change work directory
permanently?
I mean not use the function setwd() which can only change temporary, when
you close the console, it will the old directory.
Sys.setenv(R_USER = '') also doesn't work.
Hi Huidong,
There are a few ways. One is to define a .First function in the
directory where R starts and include the setwd() command in that:
.First<-function() {
setwd("/home/huidong/R")
}
If you start up a new R session, create the .First function and then
answer "y" to:
Save workspace image? [y/n/c]:
this function will be run when you start up R. You can add other
commands to customize the R session, but remember to do so in a fresh
session, then quit saving the workspace image each time you change .First.
Jim
