minor issue with "What is an R-object?" help text

[skyebend]

I'm pretty sure the help text for "What is an R-object?" is wrong about setting the path to the new location the 'envir' argument (which controls the internal search path for the object). User should either include the full path when giving the file name, or change R's working directory. Or set file=choose.file(new=TRUE) to use a normal save dialog.

Thanks @skyebend , you are right about the 'envir' argument. I found that the function to open a dialog box is actually 'file.choose', but in any case I have modified the help text to reflect the correct instructions in commit 6095eb3
