GPA Rotation Package

Cass

Hi there,

I would like to use the GPArotation package in the R Console in JASP so that I can do factor analyses that require rotations. I have tried using the library(GPArotation) command but I keep receiving an output that says Error: there is no package called ‘GPArotation.’ This can be seen in the image below. Please let me know what I can do to use this package.

Regards

Cass

You can perform rotation using the UI directly in JASP (e.g. in the principal components analysis or the exploratory factor analysis). There's dropdown menus there to select which kind of rotation.

edit: sorry I just saw you're trying to get $rms from the fa object, is this not provided in the output using the JASP procedure through the UI? $rms: "This is the sum of the squared (off diagonal residuals) divided by the degrees of freedom."
