injurytools

Overview

injurytools is a package designed for the field of Sports Medicine. It simplifies the data analysis workflow by providing convenience functions and handy tools for sports injury and illness data.

The functions can be classified into: (a) sports injury and illness data preparation, (b) descriptive analyses and (c) data visualization routines. Further analyses, such as the estimation of the risk of injury/illness (any sports-related health problem) with other covariate effects, can be performed outside of injurytools, whether the event of health problem is viewed as count or time-to-event data.

To get an overview of the package, see the Articles section.

In practice, the package can automate specific descriptive reports that are routinely generated for sports injury and illness surveillance.

Installation

To install from CRAN:

install.packages("injurytools")

To install the most current version from GitHub:

devtools::install_github("lzumeta/injurytools")

Usage

Functions for data preparation start with prepare_*(), those for estimating epidemiological measures start with calc_*(), and those for data visualization with gg_*().

The below outlines at a glance how injurytools can help to get a comprehensive picture of sports injury and illness data:

library(injurytools)
library(ggplot2)

               by_date = "2 month") +
    ## plus some lines of ggplot2 code..

          axis.title.x = element_text(size = 20, face = "bold", vjust = -1),
          axis.title.y = element_text(size = 20, face = "bold", vjust = 1.8),

          plot.title.position = "plot")
)

            vjust = -0.5, data = injd) +
  scale_y_discrete(expand = expansion(mult = 0.05))
