Plot two matrices and keeping the record of row names
Dear Peter, Thanks for your reply.I am familiar with this solution but I was trying to make the plot user friendly.I have seen some plots,in which if we keep a cursor on any point of plot,it will automatically shows you the row names.Is it possible? I did not find anything related to this. Thanking you, Warm Regards Vikas Bansal Msc Bioinformatics Kings College London

Tena koe Vikas If I understand you correctly, you could generate a character matrix the elements of which are the row.names and col.names of x1 pasted together (perhaps with : as a separator). Then the upper.tri of this will give you the associations. HTH ...
