Parse ANKOM Timestamps

Source: R/parse_ankom_time.R
parse_ankom_time.Rd

Converts ANKOM RF timestamps into elapsed incubation time expressed in hours.

Usage

parse_ankom_time(time_raw)

Arguments

time_raw

Character vector containing ANKOM timestamps.

Value

A numeric vector containing elapsed incubation time in hours.

Details

ANKOM RF systems record measurements using timestamps. This function converts those timestamps into elapsed incubation time, measured relative to the first observation.

The resulting values are used throughout rumenGP for:

  • Data processing

  • Model fitting

  • Visualization

  • Model comparison

In most workflows, this function is called automatically by process_ankom() and does not need to be used directly.
