numerical issues in chisq.test(simulate=TRUE) (PR#8224)
Hi,
This report deals with p-values coming from chisq.test using
the simulate.p=TRUE option. The issue is numerical accuracy
and was brought up in previous bug reports 3486 and 3896.
The bug was considered fixed but apparently was only mostly
fixed. Just the typical problem of two values that are
mathematically equal not ending up numerically equivalent.
Consider this series of three 2x2

alternate rank method
Hi,
I'm wondering if anyone can point me to a function that will
allow me to do a ranking that treats ties differently than
rank() provides for?
I'd like a method that will assign to the elements of each
tie group the largest rank.
An example:
For the vector 'v', I'd like the method to return 'rv'
v: 1 2 3 3 3 4 5 5 6 7
rv: 1 2 5 5 5 6 8 8 9 10
Thanks,

Documentation of colSums et. al (PR#4154)
Full_Name: Doug Grove
Version: 1.7.0
OS: Linux
Submission from: (NULL) (209.31.211.56)
Hi,
Minor mistake in the documentation on the colSums page.
In the ARGUMENTS section it states for 'dims' that:
For `col*', the sum or mean is over dimensions
`dims+1, ...'; for `row*' it is over dimensions `1:dims'.
These two are reversed.
Thanks,

Wishlist: write.delim()
Hi,
It would be great if someone would add write.delim() as an
adjunct to write.table(), just as with write.csv().
I store a lot of data in tab-delimited files and can read
it in easily with: read.delim("text.txt", as.is=TRUE)
and would love to be able to write it out as easily when
I create these files.
The obvious setting needed for write.delim() is sep = "\t",

error in help.search (PR#14113)

Version: 2.10.0 10-26-2009

Submission from: (NULL) (140.107.164.65)
Hi,
Looks like the revisions to help.search didn't get completely finished.
When the user specifies the argument 'package' the code doesn't define the
variable 'paths' prior to trying to use it, which obviously produces an error.

I just found that rank() has a 'decreasing' argument that is not documented in

it is not documented there. For curiousity I also went back to version 1.8.1

R-1.6.0 crashing on RedHat6.3

I'm having what I believe are OS problems with my installation

Windows Memory Issues
Hi all,
I am currently building an application based on R 1.7.1 (+ compiled
C/C++ code + MySql + VB). I am building this application to work on 2
different platforms (Windows XP Professional (500mb memory) and Windows
NT 4.0 with service pack 6 (1gb memory)). This is a very memory

Unusual behaviour
Hi,
I've just noticed something strange in dovecot 0.99.10.5. I created
some IMAP folders from the command line (mkdir .INBOX.Folder1) as a
different user to the owner of the mailbox. Obviously when I tried to
view them via IMAP I got an error message, but the message to the client
was "internal error[date time]" where date and time appeared to be the

FW: why is it numeric(0)?
hello,everyone. I have one question:
example 1
> x=numeric(0)
> y=5
> print(x+y)
numeric(0)
example 2
> x=numeric(1)
> y=5
> print(x+y)
[1] 5
why the print(x+y) is numeric(0) at the first example, but the result is 0
at the second example?

Azure AD (Entra ID) join specification
I've made some minor changes to the join document for Azure AD.
Specifically, there was a major mistake in the TransportKey definition.
If you're working on a join implementation, make sure you pay close
attention to the changes. Azure accepts just about any blob in the
TransportKey field, and doesn't perform any validation on it. This only
becomes obvious when future responses

Choice of text for intermediate level R programming course
The Subject line mostly says it. I'm designing it as a semester-long, 3
hours per week, course
that takes in students who got the basics of R in stats classes, but don't
really know how to
program in it. Translation: if their own examples don't look enough like
examples from
previous work, they're stumped.

Samba permissions problem
Hi all,
I have a permissions problem with a samba share which I really
can't fathom out. I'm trying to create a fully group writable share.
Easy or so I thought.
As you can see from my config I am trying all the options to set files
group writable, however when I create a file from the client I'm always
getting the
mode 0644. Does anyone have a clue why? Thanks!

Xen - multiCPUs per socket setting?
I''m still trying to figure out how to get my Xen installation on a 34-CPU
machine (8 quad cores) to recognize more than one CPU per socket. It seems
to default to one CPU per socket on this machine. Win2003ServerEnterprise
will support 8 quad cores (32 CPUs) in a native install, but I can''t
