Creating a Heatmap in R | ComplexHeatMap tutorial p1

Google heatmap in Bioinformatics make me realize how much heatmap is being used in the world of bioinformatics research and publication. With the advancement in the codes, it is now possible for anyone with about an hours time to learn how to make a really intricate and beautiful figure without intensive knowledge in coding, or graphic design (like me, these thumbnail are created in LibreOffice draw).

While researching for how to use oncoprint, I came across this package call "ComplexHeatmap" in Bioconductor which was first publish in 2016 by Zuguang Gu and just find it impossible not to share about my journey in understanding the basics in using this package to draw out some pretty nice figures.
