My models have been running well prior to attempting to use a habitat mask. Now that I have tried to use a mask I am encountering an error that I do not know how to deal with. I tried tracing back the error's location using
- Code: Select all
>
options(error=recover)
> options(show.error.location=TRUE)
to identify where the error was occurring, but I can't make heads nor tails of it since it is pretty deep into the backend code and the objects being called are ones that I am not sure how they relate to what I have entered.
- Code: Select all
> options(error=recover)
> options(show.error.location=TRUE)
> library(secr)
> setwd("C:/Users/jpdraper/OneDrive - Auburn University 1/Master data/SECR data")
> MRBCH<-read.capthist('MRBcaptsub1415.txt', c('MRB2014.txt', 'MRB2015.txt'), detector = "proximity", fmt=c("trapID"))
No errors found :-)
> library(maptools)
> library(rgeos)
> setwd("C:/Users/jpdraper/OneDrive - Auburn University 1/Master data/mapping")
> MRBmaskin<-readShapePoly('MRB_mask_poly')
> MRBmask<-make.mask(traps(MRBCH), buffer=100, type="polybuffer", poly = MRBmaskin, poly.habitat = TRUE, spacing=500)
> g.D.S.<-secr.fit(MRBCH, model=g0~1, buffer=7500, trace=FALSE, ncores = 3, mask=MRBmask)
Error in (function (f, p, ..., hessian = FALSE, typsize = rep(1, length(p)), :
missing value in parameter
Above is the entirety of the code that I have entered and the resulting error. As sheepish as I will feel I am hoping that I just forgot an argument somewhere. Thank you for any help that can be provided
