I have had a minor but annoying problem with the Mac GUI that started with R
version 3.4.3. I am using latest versions of everything: R 3.4.4, MacOS High
Sierra 10.13.4, all packages fully updated, etc.
The command line history retains the carriage return at the end of the line.
Since you have to enter a new carriage return to send the command, the stored
command lengthens by one return every time you repeat it. So your key pattern
has to be Ctrl-p or up-arrow to repeat the command, immediately followed by
Delete to remove the final carriage return, followed by editing of the line if
that is what you want.
As I say, minor but annoying, and this behavior started with R 3.4.3 and
persisted in R 3.4.4. As best as I recall, nothing changed in the OS around
then so it seems to be an R issue. I would be very grateful for suggestions of
how to mitigate it, or if there is any proposed fix.
