sub-.camOp: Subsetting method for camera trap station operation matrices

In camtrapR: Camera Trap Data Management and Analysis Framework

Subsetting method for camera trap station operation matrices

Description

Ensures that subsetting a camOp object (e.g. x[1:5, ], x[, 1:30]) retains the camOp class and its provenance attributes (stationCol, cameraCol, sessionCol, setupCol, retrievalCol). Unlike those, the from/to attributes are recomputed from the remaining column names (dates) rather than carried over unchanged, since they describe the date range actually covered by x and would otherwise go stale after column subsetting.

Usage

## S3 method for class 'camOp'
x[i, j, ..., drop]

Arguments

x	an object of class camOp
i	row index
j	column index
...	further arguments passed to or from other methods
drop	logical, whether to simplify to a vector when selecting a single row/column
