File	Description
ema.options.R	Response options for each EMA question. Loaded by init.R.
functions.R	Helper functions, mainly for data formatting. Loaded by init.R.

read.data.R	Read and tidy up CSV-formatted data. Called by workspace.csv.R.
summary.R	Compiles summary.Rnw into summary.pdf
summary.Rnw	knitr document for the data summary. Loads csv.RData and analysis.RData, the R workspace files
workspace.analysis.R	Create a workspace file containing data frames for summary and analysis. Loads csv.RData and analysis.RData, the R workspace files created respectively by workspace.csv.R and workspace.analysis.R.
workspace.csv.R	Create a R workspace file containing data frames for the source data files
xzoo.R	Extensions for the time series R package zoo. Loaded by init.R.
ema_engagement_plots.R	Create plots of EMA engagements. Currently considers a row in engage to be an 'engagement' and treats a missing row as a true zero (lack of engagement). Need to fix: there are many cases with EMA responses but no recorded engagements, so rows in engage are not equivalent to an engagement.
