Description Usage Arguments Value Author(s) Examples

Description

Selects among a set of covariates the best set of npred predictors for a given response trait resp based on AIC values.

Usage

1
select_pred(.data, resp, covariates = NULL, npred)

Arguments

.data

A data frame with the response variable and covariates.

resp

The response variable.

covariates

The covariates. Defaults to NULL. In this case, all numeric traits in .data, except that in resp are selected. To select specific covariates from .data, use a list of unquoted comma-separated variable names (e.g. traits = c(var1, var2, var3)), an specific range of variables, (e.g. traits = c(var1:var3)), or even a select helper like starts_with("N").

npred

An integer specifying the size of the subset of predictors to be selected
