Plotting an adjusted kaplan-meier curve
Dear R-users
I am trying to make an adjusted Kaplan-Meier curve (using the Survival package) but I am having difficulty with
plotting it so that the plot only shows the curves for the adjusted results.
My data come from a randomised controlled trial, and I would like the adjusted Kaplan-Meier
curve to only show two curves for the adjusted survival: one for those on treatment (Treatment==1)

How set up CPU time
Hi all,
i know that for each virtual machine i can set up a number of vcpu. But
if i want to give only a % of the real CPU? For example: how can i set
up a virtual domain for using only 20% of the real CPU? is it possible?
Ty in advance

Plotting an adjusted survival curve
First a statistical issue: The survfit routine will produce predicted survival curves for
any requested combination of the covariates in the original model. This is not the same
thing as an "adjusted" survival curve. Confusion on this is prevalent, however. True
adjustment requires a population average over the confounding factors and is closely
related to the standardized

using function boot
Dear R Users,
I am trying to use the function boot of the boot package to sample from a dataframe of two character variables (N=1127). Each character variable can take five different values. Here is an example of the data:
1 b95-99.9 d25%
2 b95-99.9 a1%
3 b95-99.9 a1%
4 b95-99.9 a1%
5 b95-99.9 a1%

How to make this for() loop memory efficient?
##I have 2 columns of data. The first column is unique "event IDs" that
represent a phone call made to a customer.
###So, if you see 3 entries together in the first column like follows:
matrix(c("call1a","call1a","call1a") )
##then this means that this particular phone call (the first call that's
logged in the data set) was transferred

ARIMA standard error
Hi,
Can anyone explain how the standard error in arima() is calculated?
Also, how can I extract it from the Arima object? I don't see it in there.
> x <- rnorm(1000)
> a <- arima(x, order = c(4, 0, 0))
> a
Call:
arima(x = x, order = c(4, 0, 0))
Coefficients:

Assign name to object for each iteration in a loop.
Hi R-users,
I'm trying to produce decompositions of a multiple time-series, grouped by a
factor (called "area"). I'm modifying the code in the STLperArea function of
package ndvits, as this function only plots produces stl plots, it does not
return the underlying data.
I want to extract the trend component of each decomposition

Problems streaming high bitrate over a LAN
I am trying to stream various 320kbps MP3s across my 10Mbps LAN. Either locally
or across the network, freeamp and xmms prefetch a chunk, then play it, then
fetch another chunk etc. No continuous streaming. shout gets a lot of !s between
its "."s when sending the file to icecast. Any ideas?

Comparing pooled proportions(complication and reoperation rates) of different treatment modalities

I am currently writing a meta-analysis on the complication and reoperation rates of 5 different treatment modalities after a distal radius fracture. I was able to pool the rates of the 5 different rates using R. Now I have to compare the pooled rates of the 4 treatment modalities with the golden standard separately.

can't remove groups in AD
Hi,
I set up a samba 3.0.26a as an ads-member of a windows 2003 Small

Every windows user in the domain can read and write their files,

My Problem is, that I cannot set up security groups in the AD. When I

ignored.
I cannot set rights exceeding read,write, execute and owner.

Thank you very muchly. It works now. Any idea how to synchronize 2 players on
