Dear All

I was trying to make a heatmap using library(gplots)

library("gplots")
t <-(read.table("target_file",header=TRUE))
Y <-t$ID
x<-as.matrix(t[2:7])
heatmap.2(x,col=redgreen(75),Rowv=TRUE,Colv=TRUE,scale="row",key=TRUE,symkey=FALSE,
density.info
="none",labRow=Y,labCol=c("control","control","control","stress","stress","stress"),trace="none",cexRow=0.5)

My problem is, it plots a heatmap which looks very odd, I want to control
the size of box it make in heatmap.

Using margin=c(12,12) in the function reduces the picture as a whole but not
the size of boxes it makes.

Can anyone help me making the pretty heatmap

I shall be very thankful for your kind help

Regards
