aggregate slow with variables of type 'dates' - how to solve

gets bigger the larger the 'id' var is - but see this sample code:

"02/28/92", "02/01/92"))

separate date and time
I have a combined date and time. I would like to separate them out into two
columns so I can do things such as take the mean by time across all dates.
meas<-runif(435)
nTime<-seq(1303975800, 1304757000, 1800)
nDateT<-as.POSIXct(nTime, origin="1970-01-01")
mat1<-cbind(nDateT,meas)
means1<- aggregate(mat1$meas, list(nDateT), mean)
This doesn't do anything as each day

SEXP i/o, .Call(), and garbage collection.
Apologies for any obtuseness in the following. We have been working
on Version 2.0 of the randomSurvivalForest CRAN package and we're
encountering a perplexing 'memory not mapped' segfault that we believe
is "influenced" by GC.
We essentially have two R functions, rsf.default(..), and
predict.rsf(..) and two corresponding entry points, rsfGrow(...), and

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.

Problem with distributing data in package.
Hi List,
I am building a package for a client to help them create and perform
analyses against netcdf files which contain 'a temporal stack' of
grids.
For my examples and test cases, I create an example dataset in code
(as this is a lot more space efficient than providing raw data). The
code creates a netcdf file in tempdir() and an object of class 'ncdf'
in the global namespace.

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,
Heinz

Pesos en modelos mixtos
Hola a todos,
Me gustaria saber si en un modelo mixto se puede usar el tamaño de muestra como
peso o es incorrecto hacerlo.
Por ejemplo en el comando 'lmer' del paquete lme4 hay una opcion 'weights'
(igual que en 'lm' de stats). Si tengo datos de una medida (por ejemplo el
peso) de 10 especies de aves (rango, de 50 a 3000 datos segun la especie) ¿puedo

A programming question - is what I want to do possible in R?
I have a large data frame, 77 rows, with 10 columns. Each row represents a
unique individual with 10 characteristics, some of which are categorical
factors and some continuous numeric variables. Each of the ten variables is
important (the 10 columns obviously correspond to the individuals of
interest). Importantly, this data set represents a population (not sample)
of people with a certain medical

Automation of c()
Hi,
I have around 300 files with the x, y and z coordinates of a DEM that I
would like to join in a single data frame object. I know how to automate the
import of the 300 data frames.
in Bash
ls > names
in R
names<-scan(names...)
With rep() and data.frame() construct a series of read.table() commands,
which you write to a file and execute them with source().
I do not know however how

Reading in FORTRAN data using R
Hi There:
I was wondering if there is a way to read FORTRAN list data (similar to
IDL's readf function). I often use FORTRAN for most of my number
crunching, and use something like IDL to visualize and perform
statistical analysis on that data. Since the each file is rather large
(>100 Mb), formatting the output into columns or tables is impractical,
hence the "list"
