Extract message timestamps data from .asc files

Description

This function reads in data from .asc files and returns the timestamps for when the message occured. Currently supports up to 3 message at a time.

Usage

ExtractMessages(data_list = NULL, maxtrial = 9999,
  message_name = "MSG")

Arguments

data_list	Input of data files to be processed. This can be specified in three ways: a directory that contains all the files (it will select all files ending with ".asc", and order them by participant number, if present). Directory to a txt file that contains all the .asc data file names inside: e.g., data_list= "C:/My Data/data_list.txt". In the .txt file, the directory for each .asc data file should appear on a separate row, e.g.: C:/My Data/subject1.asc /n C:/My Data/subject2.asc A directory to a single .asc file: e.g., data_list= "C:/My Data/subject1.asc".
maxtrial	Maximum number of trials in the experiment (default= 9999)
message_name	Name of the message flag in the data which needs to be extracted. If only one message needs to be extracted, provide it as a string (e.g., message_name= "DISPLAY CHANGE STARTED"). If there is more than one message, provide it as a vector of string (e.g., message_name= c('DISPLAY CHANGE STARTED', 'DISPLAY CHANGE COMPLETED')).
