> How to add a common legend (a list of text, in 1 column) to 2 plots displayed by par (mfrow = c(1,2)) in a row? i don't know how to add the legend between 2 plots or for ex, in the right upper corner of the right plots in the margin of the right plots when there is no place to display the legend in the plot region (overlapping problem). Any other suggestion to place the legend is welcome.

Dear Carol,

have a look at the "lattice" package, one of whose strengths is exactly
what you've been asking for. Using it, however, is quite different from
using the ordinary R plotting functions, so you will probably need to
invest some time & effort learning the new way. But it's an investment
that pays off very nicely!

Best wishes
 Wolfgang
