How can I got PCs (principle components) from flashpcaR

[Chunkao Wang]

when I run flashpcaR like:

> f = flashpca(geno, ndim=10)

> str(f)
List of 5
 $ values    : num [1:10] 3.19 3.18 3.17 3.16 3.15 ...
 $ vectors   : num [1:3000, 1:10] 0.00489 -0.02114 -0.02578 0.02533 -0.02576 ...
 $ projection: num [1:3000, 1:10] 0.00874 -0.03779 -0.04607 0.04527 -0.04604 ...
 $ center    : num [1:10000] 0.998 1.022 0.992 1.013 0.998 ...
 $ scale     : num [1:10000] 0.707 0.707 0.707 0.707 0.707 ...
 - attr(*, "class")= chr "flashpca

Could you tell me where I can get first PCs and second PCs?

Thanks

Chunkao

Hi Chunkao,

The 'projection' matrix is the PCs (column 1 is PC1, column 2 is PC2, etc).
