Error duplicated events. How to formalize multiple, unbalanced, sampling of the same population #155
Description
I have multiple populations of wich sampling was performed repeatedly in different years. The sampling is not balanced, so the number of individuals is not the same across years or populations.
If I write one sample event for each individual (following the manual, page 7: "It is worth stressing here that samples are
considered in the same order as they appear in the data file. The number of lines will thus be exactly equal to the number of samples in the datafile."), I get an error stating that there are "duplicated events" since some populations have multiple individuals each year (thus identical "year, sample, pop" lines for the same pop).
I cannot imagine of other way of coding this, since simply writing the scenario as in the first example of the manual (page 9, copied below) doesn't allow me to specify the number of individual sampled each year.
Ne
0 sample 1
3 sample 1
10 sample 1
Is the only alternative to generate "artificial" populations for groups of samples collected from the same populations but at different years?
Thanks in advance
