getDiffMatrices: Calculate the Mean Ancestry Proportion Excluding Each
Chromosome/Chromosomal Segment in Turn
Description
A helper function to calculate the mean ancestry proportion for a
given subpopulation, excluding each chromosome/chromosomal segment
in turn.
Usage
getDiffMatrices(chrAncest, diff = TRUE)
Arguments
chrAncest
A data.frame holding the ancestral proportions;
each row corresponds to a sample and each column corresponds to a
chromosomal/chromosomal segment ancestry proportion.
Note: only include the proportions for one ancestral population at a time.
diff
A logical argment indicating whether the difference
between the pooled mean and the chromosomal mean should be returned,
or whether simply the pooled mean should be returned.
Value
A matrix of chromosomal ancestry differences.
Details
This function calculates the mean ancestry proportion of a given
subpopulation excluding each chromosome in turn.
