convertLotekCDMAFile: Convert Lotek CDMA log to csv

In hugomflavio/actel: Acoustic Telemetry Data Analysis

Convert Lotek CDMA log to csv

Description

Lotek CDMA logs are exported in TXT, and contain several chunks of of information. Importantly, the detections may be saved with a GMT offset, as opposed to the more common UTC standard. Additionally, the date format isn't the standard yyyy-mm-dd.

Usage

convertLotekCDMAFile(file, date_format = "%m/%d/%y")

Arguments

file	the file name.
date_format	the format used by the computer that generated the file

Details

This function extracts the detections from the CDMA file, converts the dates to yyyy-mm-dd, binds the time to the date and resets it to UTC, and ultimately converts the dataframe into the standard format accepted by actel.

Value

A data frame of standardized detections from the input file.

Examples

# create a dummy detections file to read
dummy_file <- tempfile()
sink(dummy_file)
cat(
