randomisation
Dear useRs
I am looking for a way to randomise the values within a matrix:
the conditions are that the sums of the rows and the sums of the columns should
remain the same as in the original matrix.
Any help would be appreciated
Cheers

Randomization for block random clinical trials
Hi,
I’m new to R (just installed today) and I’m trying to figure out how to do
stratified randomisation using it. My google search expedition has lead me
to believe that blockrand package will most probably be the answer to it.
I’ve played around with blockrand for awhile and tried the sample code:
library(blockrand)

male <- blockrand(n=100,

Genstat into R - Randomisation test
Hello everybody,
I have a question. I would like to get a correlation between
constitutive and induced plant defence which I messured on 30 plant
species. So I have table with Species, Induced defence (ID), and
constitutive defence (CD). Since Induced and constitutive defence are
not independant (so called spurious correlation) I should do a
randomisation test. I have a syntax of my

Randomisation tests
Hi,
I want to ue a randomisation test, to compare two sample means, for a
small set of data, I've looked at towt.permutation, perm.test and
permtest, as well as permTS(), which is the best one to use for such a
simple purpose? I know perm.test package isn't used anymore and coins
recommended, but reading the manual I couldnt find the function most
like it, ore more likely I

[compiler-rt] Use of ESR context in AArch64 sigframe
Hi all,
As part of some recent work to harden the Kernel Address Space Layout
Randomisation (KASLR) implementation in arm64 Linux, I've proposed a
patch for the kernel which omits the ESR context from the signal frame
if the faulting virtual address is outside the range of addresses which
can be mapped by userspace.

[LLVMdev] Entry block (Randomisation)
Hello,
In an attempt to randomise the basic blocks in a function, is it possible that I can randomise the entry block as well? And maybe insert some instructions in the pass to call entry block while running the program ?
Is it feasible?
What does entry block consist of ?
Thanks

Forcing a variableinto a model using stepAIC
Dear All,
I am attempting to use forward and/or backward selection to determine
the best model for the variables I have. Unfortunately, because I am
dealing with patients and every patient is receiving treatment I need
to force the variable for treatment into the model. Is there a way to
do this using R? (Additionally, the model is stratified by
randomisation period). I know that SAS can be

order() with randomised order in ties?
Hi
I want to use order() to get the order of a vector.
But I would need a different behavior when ties occur: similar to the
parameter ties.method = "random" in the rank() function, I would need
to randomise the ties. Is this possible?
Example:
x <- rep(1:10, 2)
order(x)
[1] 1 11 2 12 3 13 4 14 5 15 6 16 7 17 8 18 9 19 10 20
order(x)
[1] 1 11 2 12 3 13 4 14 5 15

nested cross-sectional design using lmer or nlme
Dear all, I'd appreciate some advice on the following problem. I'm
attempting to analyse a nested cross-sectional design in which an
intervention was offered to a series of randomly selected (small)

available individuals in each community were interviewed before the

Randomised variables from sql

Storing p-values from a glm
Hi,
for example one could do it this way:
v <- summary(fit)$coefficients[,4]
the coefficient attribute is a matrix, and with the "4" you refere to the
pvalue (at least in lm - don't know if summary(glm) produces sligthely
different output).
to skip the intercept (1st row): v <- summary(glmfit)$coefficients[-1,4]
hope this helps,
Arne
