Hi,
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.
Bests,
Renaud
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
str(f)
# no srcref data
str(myfun)
str(selectMethod(myfun, 'numeric'))

Responding to my own question here.
It appears I had overlooked the results from my sample script, as they
in fact do contain srcref data, but simply do not show them up in str():
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
str(f)
# no srcref data
str(attr(myfun, 'srcref'))
str(attr(selectMethod(myfun, 'numeric'), 'srcref'))
So no worries.
Renaud
