as.data.frame: Coerce capthist to Data Frame

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, ...)

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)

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.

Details

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

Examples

# NOT RUN {
  as.data.frame (captdata)
  as.data.frame (traps(captdata))
  
# }
