R Package for Downloading FIRST API Data

[Ether]

Cut it by a factor of 10. Seriously.

If there is any interest in learning how to do this within the R community please let me know and we can work it out together.

I took the world OPR data and made a graph.

EDIT: I made a better graph.

I created version 2.0.0 of the firstapiR package for downloading and manipulating FIRST API scouting data using the R language.

Here’s a link:

Once I started using the package to do OPR calculations, I realized it needed some improvements, specifically in how the data frames are shaped.

My method requires 13 seconds on a Surface 4 with an i5 process and 8 Gb of memory. It actually takes more time to create the A matrix (9 seconds) than it does to solve for the OPRs once the A and B matrices are prepared (3 seconds). The remaining second is required for reading the data and preparing the B matrix.

I am aware I am beating a dead horse here :deadhorse: , but using unmodified Sirwin’s code I am getting ~12 seconds with an i7-6560U (2.2GHz) and 8gb of RAM, memory usage is low so we can eliminate that as a factor. The bottleneck is (unsurprisingly) CPU clock cycle speed.

I’m using firstapiR v2.0.0

I am getting ~0.93 seconds on a 10-year-old Pentium D desktop running 32-bit XP with 1G RAM.

:ahh: I obviously am doing something not quite right…

Your results look about right for R code that uses dense matrix technology.
