Playing with adding + operator for easily joining geojson objects together into a single valid geojson object. This is relatively easy with lists, but not so easy with json unless you speak json.

Get lawn package too for viewing data

What if a function in a package has no examples? Or is poorly exampled? Wouldn't it be nice to find functioning instances of it "in the wild"?

Via Twitter, Noam Ross taught me a clever way to do such searches on GitHub. Put this into the GitHub search box to see people using the llply() function from plyr:

"llply" user:cran language:R
