Import Telemetry Fixes
A shortcut function for constructing a telemetry capthist object from a file of
telemetry fixes. Telemetry data are generally similar in format to polygon data
(see also addTelemetry).
read.telemetry(file = NULL, data = NULL, covnames = NULL, verify = TRUE, ...)
file |
character name of text file |
data |
data.frame containing coordinate data (alternative to |
covnames |
character vector of names for individual covariates |
verify |
logical for whether to check input |
... |
other arguments passed to countfields, read.table etc. |
Input data may be in a text file (argument file) or a dataframe
(argument data). Data should be in the XY format for function 'read.capthist'
i.e. the first 5 columns should be Session, ID, Occasion, X, Y. Further columns are
treated as individual covariates.
No ‘traps’ input is required. A traps object is generated automatically.
An secr capthist object including attribute ‘telemetryxy’ with the x-y coordinates, and a ‘traps’ object with detector type = ‘telemetry’
