Description Usage Arguments Details Value
Calculates the ip_score metric from the NRSA metrics. This is just the sum of the other invasice species metric scores for the site. The metric is somewhat concerning if a survey doesn't use the stock EPA invasives list, because the metrics would be incomparable. The mean might be a better metric, although not much better.

uid |
a vector of site identifiers |
result |
a vector of invasive metrics for each site. |
For the ip_score to be useful, each site must have the same number and identity of invasive species. For this implementation, the metrics are subsetted so that only the species on the original EPA NRSA list (f_myrspi, f_hydver, f_eiccra, f_nympel, f_lytsal, f_arudon, f_butumb, f_tamspp, f_rosmul, f_eupesu) are included in the calculation.
