'Leanpub' API Interface.
leanpubr Package:
The goal of leanpubr is to provide provides access to the ‘Leanpub’ ‘API’ https://leanpub.com/help/api for gathering information about publications and submissions to the ‘Leanpub’ platform.
Installation
You can install leanpubr from GitHub with:
# install.packages("remotes")
remotes::install_github("muschellij2/leanpubr")
Setting the API key
The main thing you need to do is get an API key from Leanpub. You can do this by visiting https://leanpub.com/user_dashboard/api_key if you are an author. If you are not an author, I don’t believe access to the API is possible. You can pass this api_key to functions in Leanpub (almost all prefixed by lp_), or you can set the environmental variable LEANPUB_API_KEY. You can set this in an interactive R session such as:
Sys.setenv("LEANPUB_API_KEY" = "YOUR_KEY")
or put this in your ~/.Renviron:
LEANPUB_API_KEY = "YOUR_KEY"
Example
You can use lp_book_info to get information about any book in Leanpub:
library(leanpubr)
slug = "biostatmethods"
res = lp_book_info(slug, error = FALSE, verbose = TRUE)
