[R] heatmap ploting

[Stephen HonKit Wong]

Dear Community,

I have an example heatmap plot in this link
<https://drive.google.com/file/d/15ePaR0gC2IKXm2gkeGylZ4vM_MEsWyW0/view?usp=sharing>
which was generated by java I believe, I want to make a similar plot in R.
Any clues on how to do it? Thanks.

The column is a gene, and the rows are different cancer types with
different numbers of patients. The heatmap value represents the expression
value, such as FPKM, which can range from 0 to over several hundreds.


Much thanks!

Steve
