NAMESPACEs and S4 classes
I'd like to have two packages with S4 classes with the same name but
different implementation. To that end I create a package tmpA with
setClass("A",
representation=representation(
x="numeric"),
sealed=TRUE)
setClass("B",
representation=representation(
x="numeric"))
B <- function(...)

locked environment and inheritance
...slots) another S4 class from some other package. The class
should be created in "myPkg" environment (and not global environment).
Using:
setClass("myS4class", representation("otherS4class", mydata = "numeric"),
where = topenv())
I get:
Error in assign(classMetaName(Class), def, where) :
cannot add bindings to a locked environment
I understand the fact that after "myPkg" is loaded, its namespace is sealed, but I was hoping to find a way around it.
I would appreciate any comment on this.
thank you.

Pixmap problem
Hi,
I'm having trouble writing .pnm images which I think is due to a problem
with my colour space. The pixmap object seems to be looking for 72 of 8
colours (one per cell?) which doesn't seem healthy...
> library(pixmap)
> x <- pixmapIndexed(rep(1:8, 9), nrow=6, col=rainbow(8))
> x
Pixmap image
Type : pixmapIndexed
Size : 6x12
Resolution : 1x1
