One way to do what I think you want is:

matplot(mydataframe,type="l")

The type="l" means "lines".  If subjects are columns, then each
line is a plot of one subject.  If subjects are rows, then

matplot(t(mydataframe),t="l")

will work.  (You can abbreviate arguments.)  You can also add the
lines one by one to a plot, using

lines().  Jon
