I do not see any disjoint on 2.7.0 patched (r45879) or 2.8.0 devel

Does Rmpi work with OpenMPI at all? It calls lamboot on load from LAM
MPI. I would think that mpi_initialize calls a shared library function
from LAM MPI which simply does not exist in OpenMPI or which does
something different from what it expects. If you ever make Rmpi working

It's not a problem with R, it's just fBasics is buggy! It overrides log

Dear list:
is there any good reason why 'c', 'cbind', 'rbind' etc (all defined as
'function(..., )') are generic and thus methods can be defined
whereas such quite useful functions like 'cat' and 'write' are not?
Would it not be reasonable to add such functionality? This would allow
to define S3

1) this IS a wrong list for such questions. You mention r-help, but this
is Rd (developers) and your question is completely unrelated to the

You could add a flag to your class and check if it set as a first thing
in the validity as in the example below:
setClass("foo",
representation("numeric", .validate="logical"),
prototype(.validate=TRUE),
validity=function(object) {
if ([EMAIL PROTECTED]) TRUE
## do lengthy checks
setClass("A",
representation(a="numeric",b="numeric"),
validity = function(object) {
if (length([EMAIL PROTECTED])!=length([EMAIL PROTECTED]))
return("different lengths of a and b")
if (length([EMAIL PROTECTED])==0)
return("object length is zero")
TRUE
}
)

Hi all:
following the previous discussion, it looks like plot(x) with y=NULL
still does not work correctly. If one tries for example plot(1:5) it
works, but already for plot(runif(100)) it does not. I posted the
proposed correction for plot.POSIXct and plot.POSIXlt before. Please
voice your opinio
t(1:100,x)
plot(as.POSIXlt(x))
plot(as.POSIXlt(x),1:100)
plot(1:100,as.POSIXlt(x))

Dear list:
working with date/times I have come across a problem that ISOdate and

until I looked at the implementation and the man page: "ISOdatetime and
ISOdate are convenience wrappers for strptime". In other terms, they

I would like to override the default way R formats plot axes with a

two points:
first for convenience and performance it has sense to derive your class from

I am trying to define the as.POSIXct as an S4 method for one of my
