Usage

greencrabData

Format

A list with four matrices representing eDNA sampling data (qPCR.N and qPCR.K) and trap sampling data (count and count.type).

qPCR.N

Total number of eDNA qPCR replicates at each site (row) and eDNA sample replicate (column). Data includes 20 total sites and 5 eDNA sample replicates.

qPCR.K

Total number of positive eDNA qPCR detections at each site (row) and eDNA sample replicate (column). Data includes 20 total sites and 5 eDNA sample replicates.

count

Count of green crab individuals in trap samples at each site (row) and trap sample replicate (column). Data includes 20 total sites and a maximum of 420 trap replicates. NA indicates that fewer trap samples were collected than the maximum at a site.

count.type

Integer indicating the traditional gear type used at each site (row) and trap sample replicate (column). '1' refers to Fukui traps, and '2' refers to Minnow traps. Data includes 20 total sites and a maximum of 420 trap replicates. NA indicates that fewer trap samples were collected than the maximum at a site.
