What is an RHISTORY file?
Data file created by R, a statistical computing and graphing application; contains the history of commands entered by the user during an open R session; similar to a .BASH_HISTORY file for the Bash shell; enables the user to push the up arrow to scan through the list of previously entered commands.
R automatically saves an RHISTORY file (.RHistory, without a filename prefix) in the R working directory. Additionally, the user can manually save the command history using the application menu options.
