bug with ddply+idata.frame+summarise? #123

I have recently upgraded plyr to version 1.8, and it seems like combining ddply+idata.frame+summarise is no longer worker as before. For example,

ddply(idata.frame(baseball), 'year', summarise, g = max(g))

will now throw the following error:

ddply(idata.frame(baseball), 'year', summarise, g = max(g))
Error in max(g) : invalid 'type' (closure) of argument

Anyone has the same problem?

Note same as #133
