Field Overlays for Different Factors

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)

Usage

fieldOverlays(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

The moderators should NOT be contained within the field matrix, and within the lavaan model, 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
