Getting and Cleaning Data:Reading from Web example now fully out of date

For lecture 02_03_readingFromTheWeb in Getting and Cleaning Data, google are now loading the Google Scholar page via javascript rather than delivering static text, so all anyone who tries out the lecture code will get is an error message in the content in R (which is what you get if you visit the page with javascript off and a clear web browser cache).
