Using R-3.3.1 on Linux I seem to sometimes get inaccurate stem-and-leaf plots
using stem. For example:

This plot is inaccurate since there are no values 469, 483, 484, etc. in the
data.
There's a 479, and a 493, etc. Since you only have even numbered stems
you get two decades of leaves on each line. The ones for the 460's
would precede the ones for the 470's if there were any; you can see that
does happen in that the 480's do precede the 490's.

If I remove one value from the input, then the result appears correct:
x <- c(479,482,487,493,494,494,495,496,497,498,498,499,503,504,507,507,508,

+ 557,559,561,561,563,563,567,568,569,570,572,578)

Is there a limit to the length of the input argument, a bug in the function, or
something I'm missing?
Thanks.
