Heatmap.2

Question

[Dk]

Hi everyone, I am trying to graph a heatmap for my DEGs data but I encountered some errors. This is my code:

heatmap.2(diffGenes, 
          Rowv=as.dendrogram(clustRows), 
          Colv=as.dendrogram(clustColumns),
          RowSideColors=module.color,
          col=myheatcolors, scale='row', labRow=NA,
          density.info="none", trace="none",  
          cexRow=1, cexCol=1, margins=c(8,20))

However, I got the error message:

Error in plot.new() : figure margins too large

Also, for the packages, I am using:

library(tidyverse)
library(gplots)
library(RColorBrewer)

I tried to look it up how to fix it but I couldn't figure out. Please help me out, thank you guys!

The RStudio plotting window is too small. Save it to a file, either pdf or png and then view it.
