Hi!
I'm creating heatmaps using pheatmap, to show an overview and clustering of differentially expressed genes.
In my experiment I have tons of DEGs (18000 genes across 132 samples), so the heatmap is.. well.. pretty huge!
The problem I'm running into is that the exported file is about 11MB; which makes it impossible to process afterwards in illustrator for publication.
I tried exporting using the filename=
argument of pheatmap, and using the pdf()
function.
Does anyone know a solution to reduce the filesize?
Thanks in advance,
Peter
