[R-sig-eco] Functional Response Modelling in R

[Emma De Roy]

I'm having trouble modelling predator-dependent functional responses in R
that incorporate non-random movement of predators and prey (i.e. prey
aggregation and thus an aggregative response), and habitat complexity.

To my knowledge, frair is the only R package available to fit and compare
functional response models, but this merely models traditional
prey-dependent Holling curves.
I did notice that there was once documentation for the Beddington-DeAngelis
predator-dependent FR, but these models are now deprecated.

Does anyone know of reference materials or resources that may lend
themselves to fitting and comparing functional response models in R that
incorporate the aforementioned parameters?


Thanks in advance,

Emma
