PCA analysis on TCGA bulk RNAseq data continued

To not miss a post like this, sign up for my newsletter to learn computational biology and bioinformatics.

In my last blog post, I showed you how to download TCGA RNAseq count data and do PCA and make a heatmap. It is interesting to see some of the LUSC samples mix with the LUAD samples and vice versa.

In this post, we will continue to use PCA to do more Exploratory data analysis (EDA).

Let’s further investigate those …
