Data Scrapping for Transportation Info using "R"

Recently, I was exposed to data mining and data scrapping using "R" which is a statistical relating language which has geospatial capability.   In a recent "R" blog, it was shown how to use "R" to data scrape the US census information from the "American Community Survey" for 2015.  I found one variable that is transit related and it is labeled "PublicTrans".  I do not know what it measures but you are able to bring it up for selected cities using code.  There are over 500 variables dealing with the census and it is a nice resource to know about.  Some code is shown below.  More to follow.
