Complex heatmaps are efficient to visualize associations between different sources of data sets and reveal potential patterns. Here the ComplexHeatmap package provides a highly flexible way to arrange multiple heatmaps and supports various annotation graphics.
The InteractiveComplexHeatmap package can directly export static complex heatmaps into an interactive Shiny app. Have a try!

ComplexHeatmap is available on Bioconductor, you can install it by:
if (!requireNamespace("BiocManager", quietly=TRUE))
install.packages("BiocManager")
BiocManager::install("ComplexHeatmap")
If you want the latest version, install it directly from GitHub:
library(devtools)
install_github("jokergoo/ComplexHeatmap")
Make a single heatmap:
A single Heatmap with column annotations:
ha = HeatmapAnnotation(df = anno1, anno_fun = anno2, ...) Heatmap(mat, ..., top_annotation = ha)
Make a list of heatmaps:
Heatmap(mat1, ...) + Heatmap(mat2, ...)
Make a list of heatmaps and row annotations:
ha = HeatmapAnnotation(df = anno1, anno_fun = anno2, ..., which = "row") Heatmap(mat1, ...) + Heatmap(mat2, ...) + ha
