In secr: Spatially Explicit Capture-Recapture

Write Data to Text File

Description

Export detections or detector layout or mask to a text file in format suitable for input to DENSITY.

Usage

write.captures(object, file = "", deblank = TRUE, header = TRUE,
    append = FALSE, sess = "1", ndec = 2, covariates = FALSE, tonumeric
    = TRUE, ...)

write.traps(object, file = "", deblank = TRUE,  header = TRUE,
    ndec = 2, covariates = FALSE, ...)

write.mask(object, file = "", header = TRUE, ndec = 2, covariates = TRUE, ...)

Arguments

object	capthist or traps object
file	character name of output file
deblank	logical; if TRUE remove any blanks from character string used to identify detectors
header	logical; if TRUE output descriptive header
append	logical; if TRUE output is appended to an existing file
sess	character session identifier
ndec	number of digits after decimal point for x,y coordinates
covariates	logical or a character vector of covariates to export
tonumeric	logical for whether factor and character covariates should be converted to numeric values on output
...	other arguments passed to write.table

Details

Existing file will be replaced without warning if append = FALSE. In the case of a multi-session capthist file, session names are taken from object rather than sess.

write.capthist is generally simpler to use if you want to export both the capture data and trap layout from a capthist object.

By default individual covariates are not exported. When exported they are repeated for each detection of an individual. Factor covariates are coerced to numeric before export.

For write.mask, header = TRUE also causes column names to be exposed.

Value

None
