Find maximum value from groups of values

[jaseeverett]

We regularly cross two datasets and there will be multiple coverage or probabilities for a given PU and we need to select the highest one. We have used this code in the Med and in the Coral Triangle.

  dplyr::group_by(cellID) %>%
  dplyr::mutate(eez = eez[which.max(eez_pres)],
                eez_prop = eez_pres[which.max(eez_pres)]) %>%
  ungroup %>%
  dplyr::select(cellID, eez) %>%
  distinct()

Possibly create a splnr_ function from this.
