airsis_parseData: Parse AIRSIS data string

Description

Raw character data from AIRSIS are parsed into a tibble. The incoming fileString can be read in directly from AIRSIS using airsis_downloadData() or from a local file using readr::read_file().

The type of monitor represented by this fileString is inferred from the column names using airsis_identifyMonitorType() and appropriate column types are assigned. The character data are then read into a tibble and augmented in the following ways:

1. Longitude, Latitude and any System Voltage values, which are only present in GPS timestamp rows, are propagated foward using a last-observation-carry-forward algorithm'

2. Longitude, Latitude and any System Voltage values, which are only present in GPS timestamp rows, are propagated backwords using a first-observation-carry-backward algorithm'

3. GPS timestamp rows are removed'

Usage

airsis_parseData(fileString)

Arguments

fileString
