colorectalcancer: Results from a microarray experiment comparing colorectal cancer samples and normal tissue samples.
Description
The colorectal
dataset consists: i) an named vector DE_Colorectal
, which represents the $log2$ fold changes of the genes chosen as differentially expressed between
colorectal cancer and normal samples based on data from Hong et al, 2007, using a $FDR=0.1$ and
the universe of all Entrez gene IDs available on the array, ALL_Colorectal
. These two vectors were obtained starting from the
top
dataframe which is the output from the topTable function of the limma package using the RMA processed gene expression data downloaded from
GEE (GSE4107).
The microarray platform used was Affymetrix HGU-133PLUS2.0.
