Hi Simon,
Since we've got some momentum on the R.app discussions, I figured
I'd throw this in the fray.
First, though, let me say that I quite like R.app. I've tried ESS
mode in Aquamacs EMacs, but (arriving late to the UNIX party) just
haven't been up to the task of learning all my <Alt>-this and <Meta>-
thats. For those who are "into" Macs qua Macs, I think a Cocoa-based
GUI is a great idea that should meet with increasing use.
The Editor Function List (EFL) should be made "S4-aware." The EFL
only displays entries for validity methods defined in 'setClass'
calls (and then it only displays the word "validity" in the drop-down
list (many, many times if many validity methods are defined)). It
also doesn't display any information from 'setMethod' and 'setAs'
calls, which are the primary mechanism for defining functions (the
latter, coercion functions) in the S4 system. Even though S4 is
still being developed, I don't imagine that 'setClass', 'setMethod',
'setGeneric', 'setAs' and 'setValidity' syntax will be changing, so I
don't think it would be premature to have the EFL recognize these.
I am guessing that the EFL is looking for syntax of the form '[name]
= function(...)' or '[name] <- function(...)'. I would be happy to
assist you by listing the new syntax patterns it should look for to
capture S4 function assignments. It might be very helpful to have
methods indexed in the drop-down list by generic and signature.
Franklin
