Thanks to Thomas Lumley for the very quick fix of the NextMethod(.Generic)
bug. The patch enclosed in his message to r-help fixed that problem
But..., I've got another one.
x <- 1:4
attr(x,"foo") <- "bar"
attributes(x < 4)
The "foo" attribute has been lost in the "x < 4" operation.
The blue book says that the result of binary operations should have
the attributes of the longer operand.
