Hi list,
I am not a frequent user of R. Recently I used R in principal
component analysis and got the result as a class, which has information like
standard deviation and principal components from 1 to 10. How is it
possible to extract the column corresponding to first principal component
and write it to a file
the out from prcomp command is something like this
Standard
deviations:
[1] 3.325801e+00 7.669837e-01 6.625773e-01 4.990732e-01 3.470071e-01
[6] 2.946679e-01 2.206289e-01 1.645828e-01 1.570887e-01
4.741294e-16
Rotation:
PC1 PC2 PC3 PC4 PC5
[1,] -0.07900624 -0.0824864352 0.1208419434 0.1763425845 0.089545020
[2,] -0.09114708 -0.0901675110 0.1377608881 0.2224127252 0.076620976
[3,] -0.10510742 -0.0935434206 0.1113586044 0.2513993555 0.029783117
I want to extract PC1 and 1 value in the standard deviation
Thanks
