aggregate slow with variables of type 'dates' - how to solve
Dear all
I use aggregate with variables of type numeric and dates. For type numeric
functions, such as sum() are very fast, but similar simple functions, such
as min() are much slower for the variables of type 'dates'. The difference
gets bigger the larger the 'id' var is - but see this sample code:
dts <- dates(c("02/27/92", "02/27/92",

MCMC coding problem
Dear All,
I am trying to convert some S-plus code that I have to run MCMC into
R-code. The program works in S-plus, but runs slowly.
I have managed to source the program into R. R recognizes that the program
is there; for example, it will display the code when I type the function
name at the prompt. However, the program will not run. When I try to run
the program, I get the following error

Fwd: Recall function: "evaluation nested too deeply: infinite recursion / options(expressions=)?"
hello all
i searched the archives and couldn't get a solution to the following question.
i have the following function:
F=function(z,v)
{
if (v==-.5) return(1) else return(2*v/z + 1/Recall(z,v-1))
}
and while testing whether it works (ie F(z,v) is approx = besselK(z,1+v)/besselK(z,V). the recursion formula allows one to calculate besselK(z,1+v)/besselK(z,V) for large values of z )

vfs_gpfs module errors
Hi
I'm encountering an error with some of my Windows clients when
using CTDB and samba to access a GPFS hosted share. We see the following
error all the time.

The copy continues but is slow. All the timestamps seem reasonable for
the data copied.

Forming SQL Query at run-time
Hi.
I am trying to get data from mysql database using a couple of queries.
I do one query to find out the indexes. Then i need to use these
indexes in another query, but i keep getting errors.
Here is something:

tags 516294 = upstream
thanks
Hi!
Please find attached a diff closing #516774 by adding mkstemp(3),
again with a minimalistic pseudo-arc4random(3) behind it. I?ve
revisited the code. An mkstemp testsuite from the ?net shows it
works, except for not caring how many ?X?en are in the template.
Addressing #516294, it allows compiling and linking an mksh from

ogg123 remote interface
Hi,
I've been working on ogg123 to see if i could add a remote interface
compatible with the one in mpg123. This remote interface is used mainly by
mp3 players which use mpg123 as their backend.
The reason i did this was that i have recently encoded some of my cd's in
ogg vorbis format but wanted to keep using my favourite player (playmp3list,

memory management
Hi All,
just a quick (?) question while I wait my code runs...
I'm comparing the identity of the lines of a dataframe, doing all possible
pairwise comparisons. In doing so I use identical(), but that's by the way. I'm
doing a (not so) quick and dirty check, and subsetting the data as
data[row.numb,]
and
data[a different row,]
I suspect the problem there is that I load into

survSplit with data.frame containing a Surv object
Dear All,
since years I am struggling with Surv objects in data.frames. The
following seems to have to do with it.
See below the modified example from the help page of survSplit. The
original works, as expected. If, however, a Surv object is added to
the data.frame, each record gets doubled.
Is there some solution other than avoiding Surv objects in data.frames?
Thanks,

ogg123 --end 1:59 patch.ogg
Hi
Here is another patch regarding time in ogg123 which is more
controvercial than the other one I send some days ago. (see
attachment)
When working with Daisy/SMIL [1] files it would be helpfull if the
user could stop play at a specific time. Currently .ogg files are not
allowed in the Daisy format but that will hopefully happen one day if
I work hard at it.
A clip in a Daisy file could look
