Get or set the sex of pedigree members
Functions for retrieving or changing the sex of specified pedigree members.
getSex(x, ids, named = FALSE) setSex(x, ids = NULL, sex) swapSex(x, ids, verbose = TRUE)
x |
A |
ids |
A character vector (or coercible to one) containing ID labels. |
named |
A logical: return a named vector or not. |
sex |
A numeric vector with entries 1 (= male), 2 (= female) or 0 (=
unknown). If |
verbose |
A logical: Verbose output or not. |
getSex(x, ids) returns an integer vector of the same length as ids,
with entries 0 (unknown), 1 (male) or 2 (female).
setSex(x, ids, sex) returns a ped object identical to x, but where the
sex of ids is set according to the entries of sex
swapSex(x, ids) returns a ped object identical to x, but where the sex
of ids (and their spouses) are swapped (1 <-> 2).
