Hello,

Just making sure I'm on the right track here. My input data follows this structure, where Usage is a single column depicting the usage of trap X for each of 5 sessions:

Code: Select all

#Detector   UTM_Easting   UTM_Northing   Usage   Trap_Type
s0139   666400   5509565   11011   / RT
s0143   668084   5489037   00111   / RT
s0145   669165   5488961   11101   / RT


I've input data as such:

Code: Select all

bearCH <- read.capthist("AllSRGBP_CapData.txt", trapfiles, detector ="proximity",
                        covname = 'Sex', trapcov = 'HTorRT',binary.usage = TRUE)

I have triple checked and I have no Usage values of 00000, yet the summary states that I have a usage of this value.

Code: Select all

$`2014`
Object class      traps
Detector type     proximity
Detector number   182
Average spacing   1289.264 m
x-range           633243 669165 m
y-range           5471935 5605408 m
Usage range by occasion
    1 2 3 4 5
min 0 0 0 0 0
max 1 1 1 1 1

Thoughts?

Cheers,
C

The usage summary is by occasion, confirming in your case that on each occasion there were both used and unused detectors. So I think you're on the right track.

Ah, thanks for that, Murray.
