Arguments
data
Dataset to be analyzed for R-mode Exploratory Factor Analysis
cormeth
Correlation coefficient. Type polycor for polychoric correlation coefficient (see polychor), for else see cor. If data is NULL, and data.cor is specified; cormeth will be ignored.
data.cor
Given correlation matrix. However, if data is specified, data.cor will be replaced.
method
Factor extraction method. Type pc for Principal component factor analysis, mle for Maximum likelihood estimation and prax for Principal axis factor analysis (see "References")
nfac
The number of factors
rotation
Rotation method. Type varimax for orthogonal and promax for oblique rotation.
Value
Returns a loadings class factor loading matrix
