Exploratory Data Analysis - Case Study - Swirl() not progressing

[apoorvaprabhu90]

The swirl keeps exiting midway during my session - is there any way to fix it?

This is what I got:

Now we'll change focus a bit and instead of looking at all the | monitors throughout the country and the data they recorded, we'll | try to find one monitor that was taking measurements in both 1999 | and 2012. This will allow us to control for different | geographical and environmental variables that might have affected | air quality in different areas. We'll narrow our search and look | just at monitors in New York State.

Error in eval(e, x, parent.frame()) : object 'State.Code' not found | Leaving swirl now. Type swirl() to resume.

I have tried installing fields package in r - I find that the package is still active but the lesson doesnt progress.I try logging back to the swirl each time but still fail at this point. Any suggestions please?

Thanks,

Apoorva
