box_pred_kernel | R Documentation |
A predation kernel where the predator/prey mass ratio is uniformly distributed on an interval.
box_pred_kernel(ppmr, ppmr_min, ppmr_max)
ppmr |
A vector of predator/prey size ratios |
ppmr_min |
Minimum predator/prey mass ratio |
ppmr_max |
Maximum predator/prey mass ratio |
Writing the predator mass as w
and the prey mass as w_p
, the
feeding kernel is 1 if w/w_p
is between ppmr_min
and
ppmr_max
and zero otherwise. The parameters need to be given in the
species parameter dataframe in the columns ppmr_min
and
ppmr_max
.
A vector giving the value of the predation kernel at each of the
predator/prey mass ratios in the ppmr
argument.
