Dear R users, I am trying to add a ColSideColor- bar to a heatmap created with heatmap.2. I had to adjust the width of the heatmap, for which I used "asp = 0.8". Now the ColSideColor- Bar does not fit to the width of the heatmap anymore. Does anyone have an idea, how I can adjust the width of the bar? Here is a simplified example: library(gplots) m <- matrix(1:300,30,10) heatmap.2 ( m, asp =0.8, dendrogram = "none", key = FALSE, density.info = "none", trace = "none", ColSideColors = c("yellow","orange","red","pink","purple","blue","lightblue","lightgreen","green","black")) Thanks, Anna [[alternative HTML version deleted]]
