chronos's Introduction

Chronos

Chronos is an R script that helps you analyze the distribution of time between two events.

Installing R

If you've never used R before, you'll need to install R and optionally download a tool like RStudio to run this script. Use setwd() to change the working directory to match the location of this script.

How it works

In order for the script to work, all you need to do is to generate a CSV file with two columns, one containing the unix timestamp of the first event and the second containing a unix timestamp of the second event:

1350268044,1408676495
1307322538,1350061315
1307676110,1340667657
1307661905,1337311786
1307758702,1428877904
1307654497,1385588891
1308368305,1317787248
1307657774,1428201852

Add your CSV to the data directory, then update the last line of chronos.R to reference that file instead of the example file.

To analyze the data, within RStudio simply load the script using source("chronos.R").

Here's the analysis of the included example data:
