Create a grid of values for a variate

Source: R/vrtgrid.R
vrtgrid.Rd

This function create a set of values for a variate vrt, based on the metadata stored in a learnt object created by the learn() function). The set of values depends on the type of variate (nominal or continuous, rounded, and so on, see metadata). The range of values is chosen to include, and extend slightly beyond, the range observed in the data used in the learn() function. Variate domains are always respected.

Usage

vrtgrid(vrt, learnt, length.out = 129)

Arguments

vrt

Character: name of the variate, must match one of the names in the metadata file provided to the learn() function.

learnt

Either a character with the name of a directory or full path for a 'learnt.rds' object, produced by the learn() function, or such an object itself.

length.out

Numeric, positive (default 129): number of values to be created; used only for continuous, non-rounded variates (see metadata).

Value

A numeric or character vector of values.
