I am desperate for help.
I am trying to get the RJDBC and rJava .5to work on both my windows xp
and linux Redhat EL5 Server. On both I get a
ava.lang.ClassNotFoundException when calling JDBC().
My example is
require(RJDBC)
classPath='C:\\libraries\\mysql-connector-java-5.1.3-rc\\mysql-connecto
I thought that perhaps the behavior in the previous post,
while inconsistent with the documentation, was not all that
harmful but I think its related to the following which is a potentially
serious bug. z is a list with a single numeric component,
as the dput output verifies, yet we cannot compare
Hi,
This works fine and gives 26:
setClass("A", representation(bidule="character"))
setMethod("length", "A", function(x) length([EMAIL PROTECTED]))
a <- new("A", bidule=letters)
str(a)
length(a)
But if my "length" method is broken, then str() stops working:
> setMethod("length", "A"
Hi,
It seems there are 2 slightly different ways to create a virtual
class with no slots (a kind of Java "interface"): with or without
specifying 'representation("VIRTUAL")'.
> setClass("A", representation("VIRTUAL"))
[1] "A"
> showClass("A")
Virtual Class
No Slots, prototype of class

Yesterday, before I reported the problem, I checked and found the same problem

The change in r42731 eliminating the final blank line when writing DCF
files changes the way 'append' can be used in 'write.dcf' and I was
wondering if this is intentional. Basically, I want to write a data
frame to DCF format one row at a time, so I make use of repeated calls
to 'write.dcf(append
For the most part, doing anything to an R object result in it's
duplication. You generally have to do a lot of work to NOT copy an R
object.

I have a C function, which performs a transformation
of a large integer matrix. The matrix may be of size 1.6GB,
so I can have only one copy in RAM and have to modify it
in place. This is possible using .Call and works fine. For
debugging, I need two copies of a smaller matrix and modify only
one o
