[R] Plotting Time Series Data by Month

[R. Michael Weylandt]

Glad to help!

There are definitely enough colors, but they aren't all assigned
numbers automatically: to see a list of built in ones, try colors()

You can always use a character string to specify a color as well --
but I think the easiest thing to do might be to use one of the palette
functions like rainbow() to make a whole set of colors equally spaced
throughout the rainbow.

For production/optimized colors, look into the RColorBrewer package --
there's a somewhat large body of research on the best way to choose
colors and that package will help automate that process.
