Hello,
I am trying to use the CCTpack package for R, especially the cctscree()
function, but keep getting the error message
#Console Output
>cctscree (IT)
...Ordinal (categorical) data detected
...885 respondents and 12 items
...Producing Scree Plot
Likely variables with missing values are
Error in fac(r = r, nfactors = nfactors, n.obs = n.obs, rotate = rotate, :
I am sorry: missing values (NAs) in the correlation matrix do not allow me to continue.
Please drop those variables and try again.
I don't know where there should be NAs in my data and fac()
itself is working fine. What exactly dows the error message mean and how can I get cctscree()
to work with my data?
Thanks!
