A discussion on r-help led me to look at stem.c at
https://github.com/wch/r-source/blob/trunk/src/library/graphics/src/stem.c
Lines 76-77 appear superfluous. They sit inside a condition, and set mu, as
follows:
if (k*(k-4)*(k-8) == 0) mu = 5;
if ((k-1)*(k-5)*(k-6) == 0) mu = 20;
But mu is set unconditionally to 10 on line 84, and that is followed by
conditional assignments (on line 85-6) identical to lines 76-77.
It looks like a couple of lines got left inside a condition that are no longer
needed there. If that is correct, is it worth removing the superfluous lines,
for future coders' benefit?
