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.
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:
or put this in your ~/.Renviron:
You can use lp_summary or lp_book_info,
these are identical, to get information about any book in Leanpub:
library(leanpubr)
slug = "biostatmethods"
res = lp_summary(slug, error = FALSE, verbose = TRUE)
