the command 'cd ~' will get you there .
In my Ubuntu terminal, I would type one of these two example commands (there are other commands, but I tend to mainly use the two below).cd change to home-directorypwd means display the path of the current directoryNote: pwd stands for print working directory.
The command 'pwd' will identify the full path of the present working directory.
The global default working directory is ~. Note that relative file references in your code will become invalid when you change working directories.There are a number of ways to change the current working directory:Use the setwd R function.Use the Tools | Change working dir... menu (Session | Set working Directory on a Mac).From within the File pane, use More | Set As Working Directory menu.On Windows, you can set the working directory by changing the Start in field of your RStudio shortcut.On a Mac you can drag/drop a folder onto the RStudio Dock icon to set the working directory.Alternatively, open a terminal and specify the work directory:$ open -a RStudio ~/projects/foo$ open -a RStudio .Note you can use the same terminal commands in Linux, however omit the trailing '.' in the second invocation. The first invocation sets "~/projects/foo" as the working directory, the second uses the current working directory.When launched through file association, RStudio automatically sets the current working directory to the directory of the opened file. However, if RStudio is already running, opening another file via file association will not change the current working directory.RStudio uses the .Rprofile file located in the current working directory. If there is no .Rprofile in that directory, the .Rprofile file located in the global default working directory (~/.Rprofile) is used instead.The global .RData file will be saved in your new working directory when you exit RStudio.
pwd - means print working directory, which is always the current directory.
Use the 'cd' command without any target; that always puts you in the home directory which becomes by default the working directory.
The root directory is the top level directory of the entire file system. Every branch starts from there. The current working directory is where you happen to be in the tree at the moment. If the root is always "/" and my process is in the directory /usr/local/bin/test/data, then the root directory is still "/" and my working directory is currently /usr/local/bin/test/data
The command pwd displays your current/present working directory.
The pwd command prints the working directory. The working directory is the directory you are "in", where operations on files that don't have an absolute path specified will be performed. For instance, if my working directory is /home/username/stuff, then the command echo "test" > test.txt would place the file test.txt in that directory.
