ArmaStats is a spiritual successor to the OCAP system written for Arma, that was disrupted by the transition to x64 architecture.
The goal of the project is to capture some of the data available within Arma in order to track performance, and generate After Action Reports.
The supporting code to translate data out of Arma is written in C by [TSOG] Fat_Lurch.
The statistical component of ArmaStats is written in R, and reports generated using RMarkdown, are written by [TSOG] Roqarr.
Erik's favorite variable is mooseflaps.
