Of course, I am aware of the alternate methods like coplot, par.plot, xyplot etc... I am specifically interested in using conditions/subsets with "plot"..

Thanks so much! Santosh [[alternative HTML

Dear Rxperts! A simple example where "write.csv" does not seem to accept user specified arguments.. Why? write.csv(t(1:10),"./te1.csv",quo=F,col.names=F) Warning message: In write.csv(t(1:10), "./te1.csv", quo = F, col.names = F) : attempt to set 'col.names' ignored However, write.table does fine..
