velo

velo is an R package which provides bicycle-related calculations frequently used by bike enthusiasts. So far many of these functions are spread over the web. These are often unreliable and/or intransparent mostly due to insufficient documentation. The main goals of the velo-package are:

• Bring together the most important bicycle-related calculations in a well-documented, transparent and reproducible manner. So far, velo lets you compute:
  • chain lengths.
  • the optimal combination of teeths for fixie bikes.
  • spoke lenghts.
  • the trail.
• Make them interactively usable via RShiny Apps (see the sibling velo_apps repository).

You can install the latest development version from github with

if (packageVersion("devtools") < 1.6) {
    install.packages("devtools")    
    }
if (!"lazyeval" %in% installed.packages()[, "Package"]) {
devtools::install_github("hadley/lazyeval")  
}
devtools::install_github("jannes-m/velo")

TO DO

• function calc_chain also for fixie bikes.
• build Shiny apps for all functions.
