Hello,
            I'm attempting to run a PCA on an example data set. I ran it
just fine, but I don't know how to few the output?  I listed what the
variable got stored in it, but I don't know how I can get anything else out
of it. Are there other ways to view the results?
Also, I'm confused about the last line "6  variables and  8 observations"
Aren't the rows the variables and the columns the observations?
 
(NOTE: if anyone knows a good guide for doing a PCA on an example data set,
from start to finish, it would be greatly appreciated)

> pc.cr
Call:
princomp(x = m, cor = TRUE)
 
Standard deviations:
      Comp.1       Comp.2       Comp.3       Comp.4       Comp.5
Comp.6 
1.545609e+00 1.407093e+00 9.886649e-01 7.539927e-01 2.919276e-01
2.460515e-09 
 
 6  variables and  8 observations.
