Part of Relations
Arguments
- ped
The pedigree information in data.frame format
- ids
character vector of IDs or NULL These are the IDs to which the analysis should be restricted. First-order relationships will only be tallied for the listed IDs and will only consider relationships within the subset. If NULL, the analysis will include all IDs in the pedigree.
Value
A dataframe with column id, parents, offspring,
siblings, and total. A table of first-order relationship
counts, broken down to indicate the number of parents, offspring, and
siblings that are part of the subset under consideration. Siblings are
animals with the same sire and the same dam, so half-siblings are not
counted and an animal with an unknown sire or dam has 0 siblings.
Details
Tallies the number of first-order relatives for each member of the provided pedigree. If 'ids' is provided, the analysis is restricted to only the specified subset.
Examples
library(nprcgenekeepr)
ped <- nprcgenekeepr::lacy1989Ped
ids <- c("B", "D", "E", "F", "G")
countIds <- countFirstOrder(ped, ids)
countIds

#> 1 B 0 1 0 1
#> 2 D 1 2 0 3
#> 3 E 0 2 0 2
#> 4 F 2 0 1 3
#> 5 G 2 0 1 3
count <- countFirstOrder(ped, NULL)
