WebIn any case, you have 2 options: transform your DESeq2 normalised counts via variance stabilisation or regularised log (setting blind = FALSE, in either case), and then directly running pheatmap on the transformed expression levels, setting scale = 'row', i.e., pheatmap (..., scale = 'row').
WebInteractiveComplexHeatmap is an R package that converts static heatmaps produced from ComplexHeatmap package into an interactive Shiny app only with one extra line of code. The first example is the default layout of the interactive complex heatmap widget.
