Hi,

I want to cluster rows in heat map but don't want the dendrogram shown. How can I do that. That's the code I have used

Code should be placed in three backticks as shown below

 p1<-pheatmap(assay(ntd_sub)[select,], cluster_rows=TRUE, show_rownames=TRUE,
               cluster_cols=FALSE, annotation_col=df)


sessionInfo( )

To hide the dendrogram in pheatmap you can set the argument treeheight_row or treeheight_col to zero.

Do note that pheatmap is a CRAN package, so you should probably be asking your question on r-help@r-project.org, or perhaps stackoverflow.com. Or you could just use a Google search.

I don't personally use pheatmap, as I find ComplexHeatmap to be a superior alternative, and which has an argument show_row_dend which you can set to FALSE to do what you want.
