comparePCBeforeAfterPrePro: Visualize PCA before and after preprocessing expression...

Description Usage Arguments Value

View source: R/comparePCBeforeAfterPrePro.R


PCA on expression data is done using good samples surviving preprocessing. Following PCAs are calculated and shown as figures: PCA of all transcripts before preprocessing, including additional scaling, PCA of gene expression after preprocessing using only expression probes that are expressed, not overinflated regarding batch affects and beeing specific to the human genome when considering a remapping approach according to Barbosa-Moralis et al. (2010)
