Fix for plot_map and informative error message in calc_haplotypes

[covaruber]

Dear Marcelo, thanks for the excellent package. While testing the package I noticed a bug for the plot_map() function and the calc_haplotypes() function.

The first one was failing in the assert_that statements because it was mapping to the type argument instead of the parent argument so I made that change.

For the second one I found that the calc_haplotypes() function was not running for me because I didn't run the mapping function for "p1p2" but there was no informative message since I thought that running the mapping() function for "p1" and "p2" was enough. I included an informative message that I hope will help users identify the same issue I faced.

Cheers,
Eduardo

Hi Eduardo,

Thanks again for the pull request and for catching those issues.

As I mentioned in the issue thread, I’ve created the 2025_updates branch to integrate new features based on user feedback. I’ll go ahead and merge your changes into the main branch and pull them into 2025_updates.

Also, I'm planning to implement the get_haplotypes() function soon. thanks @covaruber for the great suggestion!

Best,
Marcelo
