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 )
Hi,
What (my guess) you want to define is:
setMethod( incrXByOne, myclass, function(obj) [EMAIL PROTECTED] - [EMAIL
PROTECTED] + 1;obj})
You do not need - to assign to a function argument? Its in my view
even erroneous.
This S code gives an error too.
test - function(x)
{
x$bla-x$bla + 1
}
test(1)
Error in test(1) : Object x not found
/E
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
