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.
The '.' refers to the current directory that you are working in, and the '..' refers to its parent (i.e. the directory just above the one you are now in).
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
In Linux, the utility used to display the pathname of the current working directory is the pwd command, which stands for "print working directory." When executed, it outputs the full path of the directory you are currently in. This command is commonly used in terminal sessions to confirm your location within the file system.
Another name for current path is "present working directory" (PWD). It refers to the directory where a user is currently located within the file system.
The '.' refers to the current directory that you are working in, and the '..' refers to its parent (i.e. the directory just above the one you are now in).
