Popularity of "Greg" chart #1

Hi,

great training material!

In the chapter "summarize" when trying to plot the overall number of "Gregs" born across all the years it should read:

qplot(year, tot, data = greg, geom = 'line')

instead of:

qplot(year, births, data = greg, geom = 'line')

Thanks, Markus
