pData |
A data frame containing visibility correction factors by strata, see details. |
Mdat |
A data frame ... giving the total number of possible transects in each strata. Names must match strata names in data. |
prob |
A logical indicating where to do the calculation based on detection probability or it reciprocal, vcf. |
