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)
> m
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 1 2 3 4 5 6
[2,] 3 4 3 7 8 1
[3,] 1 2 3 4 5 6
[4,] 8 7 4 1 4 3
[5,] 1 2 3 4 5 6
[6,] 4 5 8 2 1 3
[7,] 9 8 7 6 7 8
[8,] 1 3 7 3 5 0
> pc.cr<-princomp(m,cor=TRUE)
> 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.
