Adjust width of annotations in pheatmap

Question

[divya.nandakumar]

Is there a way to adjust the width of row annotations in pheatmap? or are there heatmap programs that will allow for this?

Heatmap functions have a ton of parameters in their readme. Have you read the manual thoroughly? Please show us you have invested some effort.

I went over the entire help section and also looked through the forums to see if this had been done with pheatmap and couldnt find anything. I spent quite some time (I am new to this) trying to figure out a heatmap function to draw multiple annotations. I was initially using heatmap.2 which allows for adjusting the size of the annotation but doesnt allow for multiple annotations. I currently have an image like this (https://i.postimg.cc/Y9Kh0RK3/Sample-Chip.png) when ideally i would like something around this size (made with heatmap.2) https://i.postimg.cc/7PTrm4zf/Sample-Image-2.png

That looks like a theme setting for axis.text.y and axis.ticks.y in ggplot context. Does pheatmap not have relevant settings?

EDIT: I see at least 2-3 options addressing this issue. Have you tried tweaking show_colnames or fontsize_col? What options have you tried?

It does not.

Thanks. I ended up using ComplexHeatmap. It had more options that I needed.

I faced a similar problem with pheatmap, and have switched to ComplexHeatmap, although the options are plenty, I couldn't quite figure out, how exactly to match the rownames of the matrix to its corresponding enrichment term as done in pheatmap annotations. Could you share how you solved this issue ? Thanks !!!
