calculateInvasiveScore: Calculate total invasive score

In jasonelaw/nrsa: Calculate metrics for NRSA protocol data.

Description

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.

Usage

calculateInvasiveScore(uid, metric, result, FUN = sum)

Arguments

uid	a vector of site identifiers
result	a vector of invasive metrics for each site.

Details

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.

Value

a 'metric' data.frame
