| pool {snpMatrix} | R Documentation |
Given the same set of "score" tests carried out in several studies or
in several different sub-samples within a study, this function pools
the evidence by summation of the score statistics and score
variances. It combines tests produced by
single.snp.tests or by snp.lhs.tests and
snp.rhs.tests.
pool(..., score = FALSE)

Objects holding the (extended) test results.
These must be of class
snp.tests.single.score
or snp.tests.glm
|
score |
Is extended score information to
be returned in the output object? Relevant only for
snp.tests.single.score objects |
This function works by recursive calls to the generic function
pool2 which pools the results of two studies.
An object of same class as the input objects (optionally without the
.score) extension. Tests are produced for the union of
SNPs tested in all the input objects.
