Number of mapped keys for the maps in package hgu95av2.db

Description

DEPRECATED. Counts in the MAPCOUNT table are out of sync and should not be used.

hgu95av2MAPCOUNTS provides the "map count" (i.e. the count of mapped keys) for each map in package hgu95av2.db.

Details

DEPRECATED. Counts in the MAPCOUNT table are out of sync and should not be used.

This "map count" information is precalculated and stored in the package annotation DB. This allows some quality control and is used by the checkMAPCOUNTS function defined in AnnotationDbi to compare and validate different methods (like count.mappedkeys(x) or sum(!is.na(as.list(x)))) for getting the "map count" of a given map.
