If you C&P'd exactly as you typed it, you have a ',' after the closing paren for the boxplot() function call, so the issue is a typo, not an ESS problem.

Presumably, you might want:

  boxplot(chemdata$quant ~ chemdata$param, 

with additional input on another line. Or better yet:

  boxplot(quant ~ param, data = chemdata, …

to take advantage of the formula method for boxplot().
