This page has some wonderful resources for recurrence analysis. One particularly useful resource on this site is the listing of software options for conducting recurrence analysis. After a fair amount of searching, I couldn’t find an R package that computed the metrics from a recurrence quantification analysis. The tseriesChaos package provides a function for producing recurrence plots; but, I didn’t see anything for quantifying these plots.
The script was very easy to setup on my Mac and, by using Rscript it was easy to combine with R code to (a) draw specific chunks of data for different individuals in my dataset; (b) compute and output the recurrence quantification metrics; (c) output the recurrence plot dataset for creating the actual plot; and, (d) producing the plot and creating a dataset of metrics.
I’ll clean up, comment, and post the code that I used as soon as I can come up for air.
