In Dustin-Wood/funfield: Functional Field Functions

Field Overlays for Factors, from a "Difference Score" data structure

Description

This function will split force moderators that have been specified and estimated within a lavaan model (from a previous fit <- sem(model,data) statement) into separate field matrices detailing what forces should be added to the base diagram when the moderator variable has a level of '1' (often: 1=TRUE, or Z = +1 standard deviation)

Usage

diffFieldOverlays(fitPars, fmatrix, sigOnly = F)

Arguments

fitPars	can provide as summary(fit)$pe statement in lavaan
fmatrix	details the elements comprising the field matrix
sigOnly	should only the significant associations be kept? Defaults to FALSE

Details

Moderators should be specified as y ~ x:mod rather than as y ~ mod:x (as this function assigns what follows ':' as the moderator variable).

Generally, the moderator variables should be scaled in such a manner that 0 is a meaningful point for all moderators, as this will make the base model (where all moderators = 0) more meaningful. This can be facilitated by having moderator variables by dummy-coded (values of 0 or 1), effect coded (values of -1 or 1), or standardized (M=0,SD=1). See Cohen, Cohen, West, and Aiken (2003), Chapters 8 and 9.

Value

Will return Fk list of forces added by each moderator that was specified within lavaan model
