subsetByFeatures(x, features, value = c("feature_id", "x.id", "x.idx"), ...)

Arguments

x	GeneSetDb
features	Character vector of featureIds
value	are you feature id's entered as themselves (feature_id), which is the default, or are you querying by their index into a target expression object? This is only relevant if you are working with a conform-ed GeneSetDb, and further you as a user won't likely invoke this argument, but is used internally.
...	pass through arguments

Value

A subset of x which contains only the geneSets that contain features found in featureIds

Methods (by class)

• GeneSetDb: subset GeneSetDb by feature id's

gdb <- exampleGeneSetDb()
features <- c("55839", "8522", "29087")
(gdb.sub <- subsetByFeatures(gdb, features))
