pop_Ne | R Documentation |
Estimate the effective population size (Ne). This is computed from the increase in individual inbreeding, following the method described by Gutiérrez et al (2008, 2009).
pop_Ne(ped, Fcol, tcol)
ped |
A dataframe containing the pedigree. Individual (id), maternal (dam), and paternal (sire) identities are mandatory columns. |
Fcol |
Name of column with inbreeding coefficient values. |
tcol |
Name of column with generation numbers. |
A list with the effective population size (Ne) and its standard error (se_Ne).
