I have just started using Bioconductor. I am going through the manual but I found it difficult to follow. I am analysing data from 95 chips with 9500 genes. All expression Average data differences data are in a single file. My question is how I can import my data into Bioconductor for analysis? Thanks NK [[alternative HTML version deleted]]
