Principal Components and Exploratory Factor Analysis

Description

Perform principal components or exploratory factor analysis of a set of variables. This is a wrapper around psych::principal, psych::fa, and psych::irt.fa.

Usage

factoranalysis(
  x,
  nfactors,
  rotate = "oblimin",
  fm = "minres",
  polychor = FALSE,
  return.res = FALSE
)

Arguments

`x`	a data frame of variables to be analyzed
`nfactors`	(integer) number of factors to be extracted
`rotate`	(char) rotation
`fm`	factoring (char) method. May be any method allowed for psych::fa or "principal" for principal components analysis.
`polychor`	(logical) use polychoric correlatons (via psych::irt.fa)?
`return.res`	(logical) if TRUE, return output as a list instead of simply printing the output. This is used by Iana to render the output via renderTable().
