E4_EDA_Process.part3.MatchPressesToEDA {E4tools}

Match EDA data to button pressess

Description

This function allows you to extract the data that are within X minutes before and/or after a button press. If there are no button pressess for a participant, it will issue a warning and continue with the next participant. Inputs: (1) List of participant numbers, (2) location of individual EDA files from step 1, (3) location of button presses from step 2. Outputs: (1) RDS file with EDA data before and/or after button presses (and control data), for each participant and combined.

Usage

E4_EDA_Process.part3.MatchPressesToEDA(participant_list,
  rdslocation.MatchedEDA, rdslocation.EDA, rdslocation.buttonpress,
  min.before, min.after, control = TRUE)

Arguments

participant_list

list of participant numbers NOTE: This should match the names of the folders (e.g., participant 1001's data should be in a folder called "1001")

rdslocation.MatchedEDA

folder location where you want the RDS outputs to go (make sure that it ends in /). The combined data file will go into this directory. Individual participants' data will go into a subdirectory in this folder called "individual_participants"

rdslocation.EDA

folder where rds files for individual Ps' EDA data are stored (from part 1)

rdslocation.buttonpress

location of folder where button press output is stored (from part 2)

min.before

how many minutes before a button press do you want EDA data? Enter 0 if you do not want ANY data before (i.e., you're using only data post-press)

min.after

how many minutes after a button press do you want EDA data? Enter 0 if you do not want ANY data after (i.e., you're using only data pre-press)

control

add in control cases, defaults to T (default is to specify controls from exactly 24 hours prior to the press, provided there was not a press then too)
