How to set a working directory in R

In R, you can set a working directory in this way (I use C:/temp as an example).

setwd("C:/temp")

You need to be careful about the slash.  Microsoft Windows uses backward slashes, "\", to indicate the folder structure.  R uses forward slash, "/" at least on my machine.  This may be OS-dependent, so to really determine which slash is used on your environment, try this command to know the currently working directory and see which is used:

getwd()

I got this on my personal PC ("/" is used).

"C:/Users/kaz/Documents"

Alternatively, go to File and click on Change dir… to specify the working directly.
