itscalledsoccer is a wrapper around the same API that
powers the American
Soccer Analysis app. It enables R users to programmatically retrieve
advanced analytics for their favorite players and teams, with coverage
of the following competitions:
# Install release version from CRAN
install.packages("itscalledsoccer")
# Install development version from GitHub
devtools::install_github("American-Soccer-Analysis/itscalledsoccer-r")Initialize the main class with the new method.
asa_client <- AmericanSoccerAnalysis$new()If you’re in an environment where a proxy server is required, or if
you need to need to alter any other CURL options, you can
pass any number of httr
configs when initializing the class. Use these at your own
discretion.
asa_client <- AmericanSoccerAnalysis$new(
httr::config(ssl_verifypeer = 0L),
httr::use_proxy("64.251.21.73", 8080)
)Any of the get_* methods can be used to retrieve the
same data made available in the American Soccer Analysis
app. Partial matches or abbreviations are accepted for any player or
team names. For most methods, arguments must be named.
Additionally, dataframes of complete players, teams, games, and more are
also available for joining additional information. A variety of examples
are below, and full documentation can be found here.
