[Rd] POSIXct under R-1.8.0 with Methods package

[Marsland, John]

I am having problems porting a package to R-1.8.0 where I have complex S4
classes with slots inheriting from POSIXct. For example:

> setClass("test1", representation(date="POSIXct"))
[1] "test1"
> new("test1", date=as.POSIXct("2003-10-09"))
Error in ext at test(object) : couldn't find function "%in %"

Under R-1.7.1 this worked fine and generated the following:
> new("test1", date=as.POSIXct("2003-10-09"))
An object of class "test1"
Slot "date":
[1] "2003-10-09 GMT Standard Time"

Any thoughts would be greatly appreciated ...

Regards,

John

I am working with Windows NT 4.0
