read.csv.signals: Reads and checks if the csv file has the correct structure

In MatchingPursuit: Processing Time Series Data Using the Matching Pursuit Algorithm

Reads and checks if the csv file has the correct structure

Description

Reads and checks if the csv file has the correct structure

Usage

read.csv.signals(file, col.names = NULL)

Arguments

file	File to be read and check. The first line of the file must contain two numbers: the sampling rate in Hz (freq) and the signal length in seconds (sec). The function checks whether the file actually contains round(freq*sec) samples. The two numbers must by separated by one or more whitespace characters.
col.names	Vector with column names. If not specified, default names will be created.

Value

A list is returned with: 1) data frame where rows = samples for all channels, columns = channels, 2) sampling rate.

Examples

file <- system.file("extdata", "sample1.csv", package = "MatchingPursuit")

# The first line of the file must contain two numbers:
# a) the sampling rate in Hz
# b) the signal length in seconds
out <- read.csv(file, header = FALSE)
head(out)

signal <- read.csv.signals(file, col.names = "signal_1")
head(signal$signal)
signal$sampling.rate
