Usage

stratify(g, scheme = NULL, drop = TRUE)

Arguments

g	a gtypes object.
scheme	either the column name of a stratification scheme stored in the data.frame of the schemes slot of g, or a vector or factor identifying which stratum each sample belongs to. If NULL, all individuals are assigned to a single stratum named "Default".
drop	remove samples not assigned to a stratum? (those assigned NA in stratification scheme)

Value

A new gtypes object with an updated strata slot.
