Im using the heatmap.2 function in R to create a clustered heatmap of some microarray data. My commands are written as this:
heatmap.2 (as.matrix(highly_variable_genes,col=rev(morecols(50)),trace="none", main="Top 500 most variable genes across samples",ColSideColors=col.cell,scale="row"))
But even though I have specified that I don't want that hideous cyan squiggly 'trace' over my cells, which obscures everything, it keeps coming up. I've tried re-writing the command a few different ways and cannot get rid of it. Does anyone see what I have done wrong?
This command is taken wholesale from a tutorial that has no trace over its heatmap cells so I really dont know whats going on here...unless the commands have been updated in R.
Many thanks for your help.
