An Interface to the 'Scryfall' API.
scryr 
scryr is a simple, light, and robust interface between R and Scryfall’s powerful Magic: The Gathering card search engine. It wraps the Scryfall API and makes all endpoints available as simple functions that any R programmer can use.
Installation
# Install released version from CRAN
install.packages("scryr")
You can install the development version of scryr from GitHub with:
# install.packages("devtools")
devtools::install_github("curso-r/scryr")
Usage
scryr makes it easy to process Magic cards’ data programmatically. There are many endpoints that fully support tidyverse compatible analyses. For more information, start with vignette("scryr") or the full documentation.
library(scryr)
# Find red creatures with 7 power, sorted by converted mana cost
cards <- scry_cards("c:red+pow=7", order = "cmc")
# Simple pipeline that counts how many cards of each rarity have a price
cards %>%
unnest(prices) %>%
filter(!is.na(usd)) %>%
count(rarity)
