Hi Carol, There's undoubtedly better ways to do this (maybe with ggplots2?), but this is one way: layout(matrix(1:3, nrow=1), widths=c(1,0.5,1)) plot(1:10) plot(1:10, bty="n", xaxt="n", yaxt="n", type="n", xlab="", ylab="") legend("topright", c("here is the","legend","in the middle")) plot(1:10) see ?layout Best, Jim carol white wrote: > 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 > > > --------------------------------- > > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor -- James W.

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!
