[R] Re lative paths in R?

[Glen Sargeant]

See also file.path() and create.dir(). You can use them with getwd() and
setwd() to specify and/or create subdirectories, relative to your current
working directory.  Handy because they allow you to create paths and
directories with names derived within functions.

For example, I have used them to create output directories that reflect
dates when successive data summaries were prepared.

> getwd()
[1] "C:/temp/data"

> #Changes back
> setwd(wd)
> getwd()
[1] "C:/temp"
