I am having issues with performance in the R.app console on Mac Yosemite / OS X 10.10.1.
1) While editing commands on the command line, left or right arrow gradually slows within a session from usable rates to rates like 2/second or slower. 2) Autorepeat works differently for different characters: # -> ###################################### repeats normally f -> f single character a -> popup menu of differently-accented ‘a’ characters. arrow keys on an existing command line -> navigate as expected I’m mostly irritated by the slowing navigation. On trying to generate a repeatable example, I think it happens from having lots of text in the console window: # open an R.app session # try autorepeating ‘#' across the console line while counting how many seconds it takes. # put a lot of output in the window: rnorm(100000) # Autorepeat ‘#’ for the same number of seconds and see how much of the line is filled. I get about 1/3 of the film as above. If I do a couple more rnorm(100000)s, the character insertions get queued up and slower than they typing and autorepeat. Is there a way to limit the scroll-history of the console buffer?
