R help - Aug 2011 - Entering Multiline Commands With ESS

If there's a separate ESS user mail list, please point me to it.

   I'm using emacs with ESS and want to enter multiline commands for plots.
Examples in my reference books show each line terminating with a comma so
labels and other attributes can be specified for the plot before it is
submitted for rendering. When I try to do this, however, I get an error:
> boxplot(chemdata$quant ~ chemdata$param),
Error: unexpected ',' in "boxplot(chemdata$quant ~
chemdata$param),"

   Please explain how I enter these commands.

   Got it: put the options within the enclosing parentheses.

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().
