check_node_deps: Check node module dependencies and install if missing

In noamross/rnodejs: An R wrapper for node.js

Description

Put this function in .onAttach to check and install node module dependencies on first load. This is useful because some dependencies are binary and can not be hosted on CRAN. Note that it is also run each time a function created by node_fn is called.

Usage

check_node_deps(node_package, r_package, node_dir = "node")

Arguments

node_package	the directory name of the node package in the R package
r_package	the package name which wraps the function. Must be specified as the function can't automatically detect the package inside .onAttach
node_dir	the directory where node packages are kept. Defaults to 'node', which should be a directory under 'inst' when creaing your own package
