2.2 DetectionsList objects

While Detections objects represent individual receivers, an array of receivers is stored as a list of detections objects: a DetectionsList.

detlst <- DetectionsList(det_1, det_2, det_3, det_4, det_5, det_6)
plot(detlst, main = "M\u00f6rrums\u00e5n array")
mtext("CRS: WGS 84, UTM zone 33N", adj = 0)

DetectionsList objects give handy summary tables when evaluated. Below we can see the number of sync-tag emissions/detections within the array in addition to the detections of a tagged smolt swimming by (tag id: HR-53883 & PPM-53883).

## DetectionsList
## 1, 2, 3, 4, 5, 6

You can also easily convert lists of Detections objects into DetectionsList objects.

list_of_detections <- list(det_1, det_2, det_3, det_4, det_5, det_6)
detlst <- as.DetectionsList(list_of_detections)
