The answer key to the exercise questions at the bottom of the tutorial rmd is now created. Please note that I dropped the last exercise question, which was about adding the uc_boundary polygon onto mymap using ggplot.
I dropped it because the uc_boundary data (which is from the new data2 folder) is a SpatialPolygonDataFrame class data, which means students have to extract spatial points from it and then turn it into a data frame class with lat, long, and group values. This might be a good exercise for our future workshop on spatial data analysis, but not really for the current mapping class.
