activatr

activatr (pronounced like the word “activator”) is a library for parsing GPX files into a standard format, and then manipulating and visualizing those files.

Installation

You can install the released version of activatr from CRAN with:

install.packages("activatr")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("dschafer/activatr")

Usage

library(activatr)

Parsing

activatr contains function to parse, analyze, and display GPX activities. The most basic thing you can do is parse a GPX file into a tibble:

# Get the running_example.gpx file included with this package.
filename <- system.file(
  "extdata",
  "running_example.gpx.gz",
  package = "activatr"
)

df <- parse_gpx(filename)

Visualizing

Once we have that data, we can visualize it atop a map:

library(ggmap)
library(ggplot2)
ggmap::ggmap(get_ggmap_from_df(df)) +
  theme_void() +
  geom_path(aes(x = lon, y = lat), linewidth = 1, data = df, color = "red")

For more details on how to use the package, check out vignette("activatr").
