fa.buildscale: Extract scales from an EFA object
In lillion/emittr: Hilfsfunktionen fuer die psychologische Forschung

Description Usage Arguments Value See Also Examples

given the pattern maxtrix of an EFA with more than one factor, combine items loading on one particular factor to a scale and save it in an object. Items with unclear loading pattern (i.e. non trivial loadings on more than one factor) can be either evaluated using a loading difference to the next highest loading (parameter loadingdifference) or using the Fürntratt criterion. If an item fails to meet the selected criterion it will not be included in the scale.

fa.buildscale(
  faobject,
  ladungsunterschied = 0.1,
  datensatz = NULL,
  name = "scale",
  fuerntratt = FALSE
)

`faobject`	saved fa object
`ladungsunterschied`	should loadings be assigned to a factor by loading difference
`datensatz`	data.frame containing the items
`name`	Name the objects to be saved
`fuerntratt`	should loading be assigned to factor according to Fuerntratt

either the itemnumbers per scale or objects of the scales themselves saved to the environment

fa

if(!require(psych)) {
efa <- fa(pers_data[-c(6,11,16)],nfactors = 3)
fa.buildscale(efa) # all 3 scales are correctly extracted, no items is discarded
fa.buildscale(efa,datensatz=pers_data[-c(6,11,16)]) # this saves scales to workspace
}
