which.matrix(which, n.vars)

Arguments

which

a 'bas' model object x$which

n.vars

the total number of predictors, x$n.vars

Value

a matrix representation of x$which, with number of rows equal to the length of which.models or total number of models and number of columns x$n.vars

Details

which.matrix coerces x$which into a matrix.
