R.app do not saves history while command line r does. When starting R.app
history from the command line session and all new commands from current session
are available, but when quiting R.app .Rhistory is overwritten but only commands
from command line session are saved in new file. Even if one will save history
explicitly with savehistory(".Rhistory") only commands from command line session
are saved in the .Rhistory file. .Rdata is saved correctly. History works just
fine in command line application.
