I have multiple samples vs multiple genes categorized into two categories of normal and tumor samples. I would like to generate a heat map as the below image i.e Genes vs Samples(Normal vs Tumors):
I have around 1000 genes for both the Normal vs Tumor Datasets and the number of samples are 120 for tumor and 100 for Normal using ggplot or R? I tried using the hclust method but the plot looks very bad. Any other ways to plot such high number of rows and columns ?
