Dear R Can you tell me how to change the working directory of R It's just that I have some text files that I wish to save separately from the R filing structure eg. into C:/my documents and need to change the working directory of R so that it reads these files . This means if I ever upgrade the current version of R nothing will be effected. brett Brett Stansfield Environmental Scientist - Water Quality Hawke's Bay Regional Council 102 Vautier Street Private Bag 6006 Napier Phone (06) 835-9200 extn 9334 Fax (06) 835-3601
help.search("working directory")
The R folks have worked very hard to provide good documentation. Please make
use of the Help system and other resources before posting, as the Posting
Guide asks (below).

'help.search("working directory")' identifies
"getwd", the help
file for which describes "setwd".
Similarly, "www.r-project.org" -> search -> "R site
search" for
"working directory" produced 564 hits. I checked the first 4, and
they
all mentioned either getwd or setwd.
hope this helps.

Reading the posting guide http://www.R-project.org/posting-guide.html
will tell you to specify an informative subject line in your postings.
You can change working directory by using setwd(), see help("setwd").
For example setwd("c:\My Documents") might work. I am not sure if you
need to truncate the path names to 8 characters anymore.
But if you want to read files in other directory, you can do so without
changing your current working directory. As long as you can supply the
absolute or full path, you should be fine.
For example read.delim(file="c:\My Documents\project1\datafile.txt")
would read that file into R regardless of current directory.
If you use absolute paths and if you saved the commands onto a script
file, then you can re-execute these command under whatever version of R.
I would recommend this approach since you will have a rather static
working directory.
