Distance matrix plot issue

Question

[1769mkc]

This is my code which i m using to create a distance matrix from my expression value

gendat = read.csv('PRIMARY_CELL_UBI (copy).csv',row.names = 1)
gen <- t(gendat)

dd <- as.dist((1 - cor(gen, method='spearman')/2))
View(dd)

I would like to plot something like this since my expression data consist of two condition compared with normal Im not sure if i can pass the data and plot is a heatmap or how do i proceed ?

I would like to get the cluster of genes that is formed when i make the distance matrix

Any suggestion or help would be highly appreciated

Google for R heatmap.

yes i create heatmap using pheatmap ,gplot etc .But i never did a distance matrix and used that to plot heatmap.But i would be glad if you could suggest me something more to my code....

Going through the examples for heatmap.2 should enable you to do what you want.
