[R] SPSS R-Menu for Ordinal Factor Analysis

[Till Below]

Dear all,

I am trying to conduct an enhanced version of factor analysis with a 
SPSS interface that allows to use R. This approach has been suggested in 
the recent article:

Basto, M. and J.M. Pereira  An SPSS R-Menu for Ordinal Factor Analysis. 
Journal of Statistical Software 46, pp. 1-29.

My variables are ordinal-type and the tool of Basto allows to run 
polychoric correlations in the SPSS environment with the R essentials 
ans Plugin.

I used R 2.10 version for spss 20 (I only have access to spss 20). I 
loaded the required packages. When running the factor analysis in spss 
with the plugin I receive the error message posted below. Aparently, the 
tool of Basto runs only with spss 19. Since the packages and the plugin 
are installed I think it must be a problem of the spss version.

Could someone suggest me a solution for the problem? I am not familiar 
with R, and so I would prefer to run the factor analysis in spss. Is 
there any possebility to run it with spss V. 20?

Best regards and compliments for your work,
