Scraping the Web in R

Scraping the Web in R

There are times when we need to scrape some data from a website to use in our analyses. In a perfect world, the provider of the data would provide a csv or json download but let’s face it… we do not live in a perfect world and often data that is posted to the internet is done by people who really do not care about subseqent use by others (else they would have made it easy to use rather than just showing it).

Developing Online Content

Actually, it has been ‘upgraded’ a bit since I took that image. Here is what it looks like today as I start the day’s “Series of Zoom Conferences” With everything up in the air, it is critical to be able to produce as high a quality teaching experienceas possible.

Biography

I am from Seattle Washington, though I’ve been sequestered in Richmond Virginia for a job since 2004. I see RVA as the “Portland of the East Coast” and we’ve generally enjoyed our time here in the Old Dominion. My personal interestes include fermenation sciences (beer, wine, cheese, vegitables), computer programming, fly fishing, and generarlly just spending time with my family.

Professionally, I’m a Full Professor at Virginia Commonwealth University currently serving as the Director of the Center for Environmental Studies. My research focuses on understanding how landscape configuration and human mediated alteration influence connectivity amongst native and introduced species of plants and animals. Here are my Curriculum Vitae and Google Scholar Profile, OrcID if you are into that kind of stuff.
