Hi-
I used to use "<<-" to do assignment inside a class method, and
just found that now it is broken in R 2.0. For example, the
following code
-----------------------------------------------------------------------
setClass( "myclass", representation(x="numeric") )
setGeneric("incrXByOne", function(obj) standardGeneric("incrXByOne"))
setMethod( "incrXByOne", "myclass", function(obj) [EMAIL PROTECTED] <<- [EMAIL
PROTECTED] + 1 )
incrXByOne( new("myclass") )
-----------------------------------------------------------------------
will give an error message like:
Error in incrXByOne(new("myclass")) : Object "obj" not found
## R failed to trace the object back to the GlobalEnv...
It used to work under R1.7 - 1.9. I don't know whether this is a
bug or a new feature...
Anyone can recommend a workaround?
Thanks, Gang
