Is it possible to put a legend on histograms -hist(affybatch.object)- so that I can see which slide is which on the plots? I have tried it with legend(x,y, legend=sampleNames(affybatch.object)), but I can't get it to work this way either. Many thanks in advance!

try this (for 6 chips), for colours and legend. >hist(data, type="l", lty=1, lwd=2, col=1:6) >legend(12, 0.25, legend=c("chip1","chip2","chip3","chip4","chip5","chip6"), lty=1, lwd=2, col=1:6) Matt

you have to say more on what you mean by "cant get it to work". this works for me: > data(affybatch.example) > hist(affybatch.example) > legend(12,0.6,sampleNames(affybatch.example),col=1:3,lty=1:3) On Wed, 10 Mar 2004, Tineke Casneuf wrote: > Is it possible to put a legend on histograms -hist(affybatch.object)- > so that I can see which slide is which on the plots?
