build.mappings {Agi4x44PreProcess} | R Documentation |
Data frame with the mappings for the PROBE ID in the corresponding annotation package
build.mappings(esetPROC, annotation.package)
esetPROC |
Expression Set object containing processed DATA |
annotation.package |
character specifying the AGI annotation package: 'hgug4112a.db','mgug4122a.db' |
Creates a data.frame: by rows it contains PROBE IDs and by columns contains "ACCNUM","SYMBOL","ENTREZID", "DESCRIPTION","GO.Id" and "GO.Terms" for each probe. Mappings are extracted from the corresponding annotation package. Usually this function is applied to an Expression Set object containing the processed data
