I'm trying to removed annotations for the heat map legend. Originally this what the heatmap looks like using the following code:
pheatmap(M.adj, annotation_col = conds, #dropData set border_color = NA, filename = "QC/QCheatmap.pdf", color = colorRampPalette(rev(brewer.pal(n=11, name="RdBu")))(100), cluster_cols = TRUE, show_rownames = FALSE, main=paste("Gene Expression (VST) of Top 1000 Variable Genes") )

heat map1

when I drop my "dataset" colm using the following piece of code, my legends is cutoff.

pheatmap(M.adj, annotation_col = conds[2,drop=F], #dropData set border_color = NA, filename = "QC/QCheatmap.pdf", color = colorRampPalette(rev(brewer.pal(n=11, name="RdBu")))(100), cluster_cols = TRUE, show_rownames = FALSE, main=paste("Gene Expression (VST) of Top 1000 Variable Genes") )

heatmap 2

anyone know how I can make it so that my legend is not cut off in the second heat map?

Hi!

You can scale the plotting text with cex. In this case the default value is cex = 1, 1.5 would correspond to 50% larger and 0.5 50% smaller. So, use different values less than 1 until you see the whole text legend.

Best regards

Hi rodolfo! Thank you!! I'll try what you suggested. I got around it by making the naming conventions of my conditions shorter. I'll try what you suggested and to see if I can keep the length of my conditions.

Thank you for you time:)
