swapping with data.frame
Hi there,
I have some data which are convenient to enter as lists. For example:
t1<-list(fname="animal1",testname="hyla",dspkr="left",res1=39.7,res2=15.0)
t2<-list(fname="animal1",testname="bufo",dspkr="left",res1=14.4,res2=56.1)

function in R for my exercise
Hi R helpers!
I have a question. I'm trying to create a function for an exercise. Here are
the arguments I should include:
x and y are numeric
z is a name ("plus","minus","multiply","divide")
and swap is logical.
Here is what the function should do:
When z="plus", then x+y is performed and so on for the other z names. It
should give a NA

p-values pvclust maximum distance measure
Hi,
I am new to clustering and was wondering why pvclust using "maximum"
as distance measure nearly always results in p-values above 95%.
I wrote an example programme which demonstrates this effect. I

question about optim
Dear R-users,
I would like to use optim( ) to minimize a function which depends on 4 parameters: 2 vectors, a scalar, and a matrix.
And I have a hard to define the parameters at the beginning of the function, and then to call optim. Indeed, all the examples I have seen dont treat cases where parameters are not all real.
Here is my code, it doesnt work but its just to show you where is exactly my

problem with optim()
Dear R-users,
I would like to maximize the function g above which depends on 4 parameters (2 vectors, 1 real number, and 1 matrix) using optim() and BFGS method. Here is my code:

g=function(x)
{
x1 = x[1:ncol(X)]
x2 = x[(ncol(X)+1)]
x3 = matrix(x[(ncol(X)+2):(ncol(X)+1+ncol(X)*ncol(Y))],nrow=ncol(X),ncol=ncol(Y))
x4 = x[(ncol(X)+1+ncol(X)*ncol(Y)+1):length(x)]

anova(lme object)
Hi,
I use lme to fit models like
R> res1 <- lme(y~A+B, data=mydata, random=~1|subject)
R> res2 <- lme(y~B+A, data=mydata, random=~1|subject)
(only difference between these two models are the
sequence in which the indep variables are written in
formula)
where y is continuous and A, B, and subject are
factors. To get ANOVA table I used
R> anova(res1)
R> anova(res2)

strange `nls' behaviour
I initially thought, this should better be posted to r-devel
but alas! no response. so I try it here. sory for the
lengthy explanation but it seems unavoidable. to quickly see
the problem simply copy the litte example below and execute
f(n=5)
which crashes. called with n != 5 (and of course n>3 since
there are 3 parameters in the model...) everything is as it
should be.

initial points for arms in package HI
Dear R-users
I have a problem choosing initial points for the function arms()
in the package HI
I intend to implement a Gibbs sampler and one of my conditional
distributions is nonstandard and not logconcave.
Therefore I'd like to use arms.
But there seem to be a strong influence of the initial point
y.start. To show the effect I constructed a demonstration
example. It is reproducible

How to get the test statistic corresponding to the p-value in mtable?
Dear R-Users,
I want to use mtable from package "memisc" to produce Latex-style estimation
output. However, mtable() only gives me a p-value and not the corresponding
test-statistic. Does anyone know how to extract it, either from a glm/anova
object or mtable? Here is a short example:
# Run this ####################
install.packages("memisc")
library(memisc)

MCMCpack combining chains
Deal all, as MCMClogit does not allow for the specification of several chains, I have run my model 3 times with different random number seeds and differently dispersed multivariate normal priors.
For example:

res2 = MCMClogit(y~x,b0=1,B0=0.01,data=mydat, burnin=500, mcmc=5500, seed=5678, thin=5)

[LLVMdev] LLVM Newbie. Questions about backend.
Hello,
I have been studying LLVM and started to create a new backend for a
new RISC architecture. Now I need some help to get forward with my
project. I'm quite new to compiling techniques so I'm sorry for the
stupid questions.
Question 1:
My idea is to lower the select SDNode as follows:
%res1 = %falseVal
%res2 = setc %trueVal, %condition
Where setc is conditional mov. The

Formula in lm inside lapply
I am trying to run separate regressions for different groups of
observations using the lapply function. It works fine when I write the
formula inside the lm() function. But I would like to pass formulae into
lm(), so I can do multiple models more easily. I got an error message
when I tried to do that. Here is my sample code:

x2 <- rnorm(100,1)
