wave_extract: Extract a specified waveform from a labeled dataset

In LylChun/epgminer: Analysis of EPG data

Extract a specified waveform from a labeled dataset

Description

The function wave_extract subsets data and returns the specified waveform.

Usage

wave_extract(data, wave, number = 1)

Arguments

data	A dataframe containing three columns: time, volts, waveform.
wave	Desired type of waveform, e.g. pd1
number	Integer denoting which instance of the specified waveform type to select - e.g. number = 1 will select the first instance of waveform type specified by wave parameter.

Details

If the wave parameter input does not exactly match a waveform label in the data, the function will not work.

Value

A list containing 2 entries is returned: entry one is a tibble of time, volts, waveform is returned containing just the specified waveform instance. List entry 2 is the number/count of that type of waveform - e.g. if wave = "pd2" and there are 12 pd2 instances in the dataset, this entry will return 12.
