[Rd] Extracting srcref for S4 methods

2012-07-05 Thread Renaud Gaujoux 

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.

[Rd] Feature request: workaround for 'Sys.timezone()' issue for German MS-Windows

2012-07-05 Thread Janko Thyson 

Dear list,

I know this is *not* R's but Windows fault, at least for the German 
version. But: `Sys.timezone()' will return with an invalid time zone.


I just wondered if there's a chance to implement an alternative, 
"OS-independent" way for querying the time zone corresponding to the 
country where a specific R session was launched.


I've written a post on SO where I had a go at it, but it involves way to 
many steps: 
http://stackoverflow.com/questions/11347854/retrieve-time-zone-based-on-locale-country-information-in-an-os-independent-wa


It'd be really great if someone could consider addressing this.

Thank you very much,
Janko Thyson
