I obviously cannot predict the implications as much as John, but would the
followings be solutions:
- setClassUnion looks up for subclasses of its elements and add them up,
and setClass('A', ...) would update the union classes of any superclass of
'A'. removeClass would need to do some cleanup, wh
Hi,
Note sure why but subsetting by name is *very* slow when the character
vector used as subscript contains a lot of "invalid" names:
x <- c(A=10L, B=20L, C=30L)
subscript <- c(LETTERS[1:3], sprintf("ID%05d", 1:15))
> system.time(y1 <- x[subscript])
user system elapsed

I can reproduce this (exactly the same output) on Windows:

No need for generic functions and methods. Just looking at the
hierarchy of the classes shows the problem.
With Martin's simplified version:

Hi,
I'm running into more issues when reading data from a gzfile connection.
If I read the data sequentially with successive calls to readBin(), the
data I get looks ok. But if I call seek() between the successive calls
to readBin(), I get corrupted data.
Here is a (hopefully) reproducible examp
