on R version 2.15.1 (2012-06-22) (Platform: i686-pc-linux-gnu (32-bit)) sourced functions have srcref attached as an attribute. Are such data also available for S4 generics and methods? How? (See sample code below)
Thank you.


f <- textConnection(
f <- function(){}

setGeneric('myfun', function(x, ...) standardGeneric('myfun'))

setMethod('myfun', 'numeric', function(x, ...){ 'myfun,numeric' }) ")
source(f, keep.source=TRUE)

# there are srcref data for functions

# no srcref data

str(selectMethod(myfun, 'numeric'))
