Posted on Coursera discussion forum:

Look at this please, the qplot thickens! Back to swirl, attempting the qplot with same result, then I simply rerun the same qplot command & it works! I get the result in the plot window but I am no longer in swirl, it just dropped away. BTW, I'm in Mac OS X 10.9.5

| Oh, there are 38 models. We're interested in the effect engine displacement (displ) has on highway gas mileage (hwy), so we'll use the ggplot2 command qplot to display this relationship. Run qplot now with | three arguments. The first two are the variables displ and hwy we want to plot, and the third is the argument data set equal to mpg. As before, this allows us to avoid using the mpg$variable notation for | the first two arguments.

qplot(displ, hwy, data = mpg) Error in (function (expr, val, ok, vis, data = e) : object 'PANEL' not found qplot(displ, hwy, data = mpg)

Y'know, it's several months since I dealt with the issue. I believe I did find a solution but it just came about by fiddling around with it & I can't seem to remember anything more specific. Sorry.
