Animal locations (cellIDs)

Usage

data("locations")

Format

A data frame with 444 attempted deer locations and the following 2 variables.

unitID

Cell IDs. Must use the same name in the "habitat" file. Missing fixes need to be represented by = NA in the data.

fixAttempt

Integers representing sequential fix attempts. Locations are sorted accordingly. fix = 1 for first attempt (always successful) fix = 2 for second attempt (successful or not) fix = n for the nth (final) fix attempt (always successful)

Details

Cell ID values should represent which cell the animal was in at every fix attempt, so NA's exist when the GPS unit failed to record a reliable location. The 'fix' column is unnecessary for analysis because we have assumed that you have sorted the data by date and time or fix attempt. Thus, this is just a reminder to double-check.

This data is from Nielson et al. (2009).
