Description Usage Arguments Value See Also Examples

View source: R/onefactor.R

Description

Convert file containing values from stepwise lmer models to a three-dimensional array in the workspace (one-factor design only).

Usage

1

Arguments

fname

Name of the file containing output from mcRun calling either fitstepwise or fitstepwise.bestpath.

Value

Returns either a three dimension array (if file is the result of fitstepwise.bestpath) or a list of two three dimensional arrays if fitstepwise was used, one for forward and one for backward selection. Each array has the following dimensions:

run

the Monte Carlo run

crit

the alpha level for selection

params

the resulting values from individual calls to

fitstepwise or fitstepwise.bestpath

See Also

fitstepwise, fitstepwise.bestpath.
