[R] Extracting Factor Pattern Matrix Similar to Proc Factor

[Scott Colwell]

Hello,

I am fairly new to R and coming from SAS IML. I am rewriting one of my MC
simulations in R and am stuck on extracting a factor pattern matrix as would
be done in IML using Proc Factor.  

I have found the princomp() command and read through the manual but can't
seem to figure out how to save the factor pattern matrix.  I am waiting for
the R for SAS Users book to arrive. What I would use in SAS IML to get at
what I am looking for is:

PROC FACTOR Data=MODELCOV15(TYPE=COV) NOBS=10000 N=16 CORR
OUTSTAT=FAC.FACOUT15;
RUN;

DATA FAC.PATTERN15; SET FAC.FACOUT15;
IF _TYPE_='PATTERN';
DROP _TYPE_ _NAME_;
RUN;

Would any SAS IML to R converts be able to help me with this?

Thanks,

Scott Colwell, PhD
