The function heatmap.plus (library: heatmap.plus) can do that, just combine the different color vectors with cbind(col1,col2). Unfortunately the arguments required for heatmap, heatmap.2 and heatmap.plus are slightly different. r For example, I can make one side color bar (col1) with the following code: > ----------------------------------- > library(gplots) > > mat <- matrix(sample(1:100,40),nrow=5) > class1 <- c(rep(0,4),rep(1,4)) > col1 <- ifelse(class1 == 0,"blue","red") > class2 <- c(rep(1,3),rep(2,5)) > col2 <- ifelse(class2 == 0,"yellow","green") > > heatmap.2(mat,col=greenred(75),ColSideColors=col1,trace="none", > dendrogram = "column",labCol = NULL) > > > ----------------------------------- > How can I modify the code so that both col1 & col2 are displayed in the > heatmap? > thanks! > > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
