Re: PSPP crashes on Lion

[John Darrington]

Like Nick says.  Simply run a Factor analysis and select the 
scree plot checkbox.

Try something like the following syntax (/PLOT = EIGEN) is the pertinent 
subcommand:

GET FILE="1993.sav".

FACTOR VARIABLES =   famgen family16 form
        /CRITERIA = MINEIGEN (1) ITERATE (25)
        /EXTRACTION =PC
        /METHOD = COVARIANCE
        /PLOT = EIGEN
        /PRINT = INITIAL EXTRACTION ROTATION
        /CRITERIA = ITERATE (25)
        /ROTATION = VARIMAX.

     John, what did you do to reproduce the problem?  After reverting
     the fix that you pushed, I didn't get a crash running the test
     case from charts.at.
     
     Thanks,
     
     Ben.
