Hi
I am running a PCA analysis using prcomp function on my FPKM data from Rnaseq analysis.
I am scaling the FPKM data by using zFPKM from here (www.bioconductor.org/packages/release/bioc/html/zFPKM.html)
The zero values in FPKM data are converted in -Infinite, so when I run prcomp funtion, I get
Error in svd(x, nu = 0, nv = k) : infinite or missing values in 'x'
Can you help me, please? Should I just remove the -infinite?
