as.data.frame: Coerce capthist to Data Frame or Array

Description

Method for generic as.data.frame function that partially reverses make.capthist.

Usage

# S3 method for capthist
as.data.frame(x, row.names = NULL, optional = FALSE, covariates = FALSE, 
                                    fmt = c("trapID", "XY"), ...)
# S3 method for traps
as.data.frame(x, row.names = NULL, optional = FALSE, usage = FALSE, 
                              covariates = FALSE, ...)
# S3 method for capthist
as.array(x, ...)

Value

A data frame or list of data frames (in the case of a multisession input).

For capthist objects --

The core columns are (Session, ID, Occasion, TrapID) or (Session, ID, Occasion, x, y), depending on the value of fmt. Additional columns for covariates and signal strength (detector `signal') are appended to the right.

For traps objects --

The core columns are (x, y). Usage columns are named u1, u2, ..., uS where S is the number of occasions.

The as.array method for capthist objects returns an object with the same dimensions and dimnames but different class, or a list of such objects in the case of multisession input.

Arguments

x: capthist object
row.names: unused argument of generic function
optional: unused argument of generic function
covariates: logical or a character vector of covariates to export
fmt: character string for capture format
usage: logical; if TRUE then usage columns are appended if present
...: other arguments (not used)

Details

By default individual covariates are not exported. When exported they are repeated for each detection of an individual.
