I need to create heatmap with bright colors which different values have different colors. all the enteris of my matrix is between -0.1- 0.9.
I have tried the following command, but the heatmap is not interesting. How can I make it nice with more colors such that the different values have different colors?
Here is my command :
heatmap.2(Gene, col=greenred(10), key=TRUE, symkey=FALSE, symm=F,symbreaks=T,cexRow=1,cexCol=1,margins=c(6,11), scale= "column" ,trace="none",srtCol=45) dev.off()
Here is the image :
