Classify Items

Description

Automatically classify the items in a data frame.

Usage

classifyItems(
  fm,
  Df,
  min.loading = 0.4,
  max.loading = 0.3,
  max.complexity = 2,
  itemlength = 0,
  digits = 2,
  Df.name = deparse(substitute(Df)),
  return.res = FALSE
)

Arguments

`fm`	a factor model fitted by psych::fa or principal components computed with psych::principal
`Df`	a data frame containing the items
`min.loading`	minimum loading of an item to be considered a marker of a factor
`max.loading`	maximum loading of an item on a secondary factor (i.e., the factor on which the items has its second highest loading) to be considered a marker for the primary factor (i.e., the factor on which the items has its highest loading)
`max.complexity`	maximum complexity of an item to be considered a marker item. This is only used for factor models (not for principal components)
`itemlength`	trim item text to given number characters (0 = automatic trimming)
`digits`	number of digits used in the output
`Df.name`	name of data frame
`return.res`	(logical) if TRUE, return output as a list of data frames instead of simply printing the output. This is used by Iana to render the output via renderTable().
