check_node_fn_deps: Check node module dependencies and install if missing

In noamross/quickscraper: A wrapper for the quickscrape web-scraping framework

Description

Put this function in .onAttach to check and install node module dependencies. This is useful because some dependencies are binary and can not be hosted on CRAN.

Usage

  ask = TRUE, verbose = FALSE)

Arguments

node_package	the directory name of the node package in the R package
node_dir	the directory where node packages are kept. Defaults to 'node', which should be a directory under 'inst' when creaing your own package.
r_package	the package name which wraps the function. Must be specified as the function can't automatically detect the package inside .onAttach
ask	Ask before installing dependencies?
verbose	Show verbose installation? If \textask=TRUE, user decides
