pedLInv4

<p>An L inverse matrix generated from an AlphaSimR simulation of 20 generations.
One population, ABCD, is split into four, A, B, C, D.</p>

datasets

Carry out principal component analysis (PCA) of very large pedigrees such as found
in breeding populations! This package exploits sparse matrices and randomised
linear algebra to deliver a gazillion-times speed-up compared to naive singular value decoposition (SVD)
(and eigen decomposition).
