Hi,
I am drawing a heat map using gplots of R package. The file (new4) is
having values 0 and 1 only.
library(gplots)
library(marray)
x=read.table("new4", header=TRUE)
mat=data.matrix(x)
heatmap.2(mat,
col=colorRampPalette(c("black","red"))(256),
#col=greenred(75),
Rowv=TRUE,
Colv=TRUE,
distfun = dist,
hclustfun = hclust,
dendrogram = c("row"),
scale = c("row"),
na.rm=TRUE,
trace="none",
sepwidth=c(0.05,0.05),
margins = c(25, 20),
#xlab = "" ylab = ""
labRow = NULL,
labCol = NULL,
key=TRUE,
keysize=1,
density.info=c("none")
)
I am giving two color only i.e red and black but when I am try to make the
plot it again show in gradients. Therefore, I just want to plot a heat map
with two color scheme.
Thanks in advance
Thank you
Khushwant
