Hi

I have to make Heatmap using microarray data. this data have about 10,000 genes so the figure i made is large that size is 500*35000. the number of samples are 6.

but the column name(sample name) of figure is cut .

my code is

heatmap2(as.matrix(heatmap_input[,c(2:ncol(heatmap_input))]),,trace="none",scale=zscore,lhei=c(1,5),lwid=cf(0.5,4),margins=c(2,10)cexRow=0.5,cexCol=0.9,)

You missed a comma before cexRow and I don't think the one after cexCol=0.9 is needed.

Try to play with notecex, cexRow and cexCol

You want to display 10 000 genes on a single heatmap ? It's ambitious

Sometimes in graphics device you can't see all stuff from your heatmaps. So, try exporting it in pdf and play with dimensions and margins.
