[R] multiple variable basic plot

[David L Carlson]

You have not said exactly what the problem is with the labels and thickness.
For starters, putting 406 labels on the x axis is probably not going to
produce anything legible. In your example, the row names seem to be years.
Does your data span 406 years? As for line thickness, you have not specified
line thicknesses, or line types, or line colors so you get whatever the
matplot() defaults are.
