Chapter 1 Preamble

This book is intended as a detailed guide to using a particular suite of packages for HTTP mocking and testing in R code and/or packages.




Stable version from CRAN

install.packages(c("crul", "webmockr", "vcr", "httr"))

none of crul, webmockr or vcr have compiled code, but an underlying dependency of all of them, curl does. See curl’s README for installation instructions in case you run into curl related problems.
