4.2 Navigate the tree of directory with the R console

• Get the path of the current directory (know where you are working at the moment) with getwd (get working directory):

getwd()

• Change working directory with setwd (set working directory)
  Go to a directory giving the absolute path:

setwd("~/Rcourse")

Go to a directory giving the relative path:

setwd("Module1")

You are now in: “~/Rcourse/Module1”
Move one directory “up” the tree:

setwd("..")

You are now in: “~/Rcourse”
