Combine columns from multiple scan1 permutation results
Column-bind multiple scan1perm objects with the same numbers of rows.
## S3 method for class 'scan1perm' cbind(...)
... |
A set of permutation results from
|
The aim of this function is to concatenate the results
from multiple runs of a permutation test with
scan1perm(), generally with different phenotypes
and/or methods, to be used in parallel with
rbind.scan1perm().
The combined column-binded input, as an object of class "scan1perm"; see scan1perm().
