HWClr computes the centred log-ratio transformation for
genotype counts of bi-allelic genetic markers.
Usage
HWClr(X, zeroadj = 0.5)
Arguments
X
A matrix of genotype counts (columns AA, AB and BB)
zeroadj
A zero adjustment parameter (0.5 by default)
Value
A matrix or vector of log-ratio coordinates
