I have data frame like this about 250 gene i taking a small subset of it

    gene     `WT`           `Treated`
    ACTL6A	4.5167211886	4.4304190975
    ACTL6B	-4.3730103378 -9.800779238
    ACTR5	1.3871253811	1.2086608355

I am plotting heatmap since I m using pheatmap since plotting requires a matrix that is I have to use the only the numeric matrix 
I m doing something like this 
`rownames(VD3) <- data[,1]`

`mat <- as.matrix(data[,-1])`

I can plot the heatmap but Im missing my gene name labels , How can i include it in my final plot ,any suggestion ?And Im using the pheatmap library 




Your code is a bit confusing. 
You can assign the rownames to the matrix.

    Mat = as.matrix( data[,-1])
    rownames(Mat) = as.character( data[,1])
    head(Mat)
    class(Mat)

Did this help you?
