Hi all,
I'm currently using version 28.0.0 of SPSS and to try to run polychoric correlations and then EFA to validate a binary scale of 27 items.
According to the IBM site (
R and IBM SPSS Statistics - Essentials for R), R essentials are already downloaded with SPSS and I should simply download the extensions to run my analysis (SPSSINC_HECTOR for the polychoric correlations).
However, I can't seem to get the analysis to work despite this. I also couldn't get previous RASCH analysis which also require R to work either. Therefore, I'm assuming it's an R-related issue rather than specific to the polychoric correlations or EFA.
I get the following error code in my output: Error: The following R package is required but could not be loaded: polycor
SPSS HETCOR command was unable to compute the correlations due to data conditions.
This is usually due to some variables being too far from a bivariate normal distribution.
As I've never used R before I'm really struggling here.
Do I need to 'set-up' R in SPSS in any way?
If I don't need to enable R to run the analysis, are there any obvious solutions as to why R related analyses aren't running?
Any help would very very much be appreciated!
