Is there a form of with (or an equivalent function) that can be applied
I'd like to be able to write something like (drawing from bioconductor +
trellis as an example)
xyplot(maA ~ maM | maPrintTip, object = swirl[,1]) which would be
interpreted as xyplot(swirl[,1]@maA ~ swirl[,1]@maM |
swirl[,1]@maPrintTip) (or even better, match functions not slots eg. as
xyplot(maA(swirl[,1]) ~ maM(swirl[,1]) | maPrintTip(swirl[,1])))
If there isn't, can any one offer any tips on writing such a function.
I presume I'd have to deparse the formula, match the text with the
slots/methods of the function, create the appropriate call objects and
then call them?
Thanks for you help,
