Closed:Condensing dendrogram on heatmap.2

Question

[sdbaney]

I have this heatmap that I'm pretty happy with but the dendrogram extends pretty far left. I'd like to scale it down or bring it in closer to the heatmap. I know that heatmap.2 plots it on a grid so maybe I need to restructure the plotting area with the layout function but I don't quite know how to use it. Does anyone have insight, recommendations?

Here is my code:

 > library(gplots)
> library(RColorBrewer)
> zfpkm<-read.csv("~/Desktop/myosin_tpms_revised_043019.csv")
> rnames<-zfpkm[,1]
> mat_data<-data.matrix(zfpkm[,2:ncol(zfpkm)])
> rownames(mat_data)<-rnames
> my_palette<-colorRampPalette(c("blue", "yellow"))(n=1000)
> heatmap.2(mat_data, Colv=NA, main="Myosin Heatmap", margins=c(12,9), trace="none", dendrogram="row", scale="row")

And here is the heatmap it generates. **I can't get the image to show up: https://ibb.co/10CpDqn
