R help - Jul 2009 - Comparing loadings (next to each other)

Dear colleagues,

 	I've been running some principal components analyses, which generate
tables of loadings that I'm interested in looking at. 
print(f1$rot$load,cutoff=.4) is what I use, and it gives me what I want.

 	However, I'm now interested in comparing these loadings across a few
data sets. In other words, I would like R to match the loadings on
rownames() and display them next to each other, e.g.:

Loadings:
 	PC 1	PC 2	PC 1	PC 2	PC 1	PC 2
col1	0.40		0.45		0.90
col2		0.80		0.55 
col3		0.77		0.70		0.42

...I could certainly just cbind them together, but then I can't class them
as loadings:
> class(x) <- loadings
Error in class(x) <- loadings :
   cannot coerce type 'closure' to vector of type 'character'

...and I'm very interested in using the "cutoff" feature of
print.loadings.

Any suggestions? I could go in and alter print.loadings myself, but if
there's an easier way let me know.

Many thanks,

What is "x"? What is "loadings"? Where is the reproducible
code?
