getFiles: Return a list of data frames generated from the servosphere

In wittja01/ballr: Analyze Data Generated from Syntech Servosphere Trials

Description

Import all the .csv files in a single directory and convert them to a list of data frames

Usage

getFiles(path, pattern, full.names = TRUE)

Arguments

path	A string for the file path.
pattern	A string with a unique pattern to look for in file names.
full.names	Return the full file path when TRUE or the file name when FALSE.

Details

When using the servosphere, each trial produces a .csv file that contains the data from that trial. This data should include a column for time (dT), position (dX, dY), and the stimulus. All the data files the user wishes to analyze should be in the same directory. They should also have a common naming convention to facilitate the identification of these files (i.e. "x_servosphere.csv", where x might be the date the trial was run or the unique trial ID).

Other functions in this package require that all the .csv files from the servosphere that the user wishes to analyze are contained in a list, where each item in the list is a data.table created from each .csv file.

This function makes use of the data.table package to read in the .csv files, as it is currently the fastest way to bring in such files. This function is noticeably slower when alternative csv reading functions are used and when the number of .csv files is large.

Value

A list where each item is a data.table

Examples

servosphere <- getFiles("./extdata/", pattern = "_servosphere.csv")
