Hi there,

I'm currently analyzing my RNA-seq data.

Now that I've got my GSVA result, I want to draw a clustering heatmap with it. I'm using pheatmap.

> pathway_heatmap <- pheatmap::pheatmap(gsva_results, 
annotation_col = annot_df, # Add metadata labels!
show_colnames = FALSE, # Don't show sample labels
)

When I run this script, the function seems to run well without any error code coming out. But eventually, there is no image output.

If you know what causes this kind of problem or what I should re-check, please help.

Thank you a lot!
