Hi,
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.

Regards,

carol
