Count parent-offspring pairs in POP format

Parent-offspring pairs are counted between potential offspring cohort and potential parents grouped by age, year, and location of sampling. Comparisons are made only between younger and older samples.

Usage

as_pop(samples)

write_pop(x, path = "pop.txt")

read_pop(path)

Arguments

samples

A sample_family data.frame of tekka() result.

x

An outcome of as_pop()

path

A file name or connection to write to

Value

A data.frame with "pop" class and six columns:

• cohort: birth year of offspring

• capture_year: of parents

• capture_age: of parents

• location: where parents were sampled

• pops: the count of parent-offspring pairs observed within samples

• comps: the number of possible comparisons.

Details

as_pop() converts a sample_family data frame to POP format.

write_pop() writes a POP data.frame to a file.

See also

as_pop2() for the extended POP format.

Examples

set.seed(666)
result = tekka("-y20 -l2 --sa 2,2 --sj 2,2")
samples = result$sample_family[[1L]]
