I took your advice into consideration and i tried to solve my errors. But ,

Unless for learning R, you should really consider R.oo or proto packages

Yes, the secant method (like Newton Raphson) is not guaranteed to converge,
unlike the bisection method, but it has a superlinear convergence (not that

hello,
i want to stack two lattice plots beneath each other using one x-axis and
sharing the same text-panels,
like:
#
library(lattice)
y1 <- rnorm(100,100,10)
y2 <- rnorm(100,10,1)
facs<-expand.grid(Sites=rep(c("Site I","Site I
Hi all,
I have read posts of heat map creation but I am one step prior --
Here is what I am trying to do and wonder if you have any tips?
We are trying to map sequence reads from tumors to viral genomes.
Example input file :
111 abc
111 sdf
111 xyz
1079 abc
1079 xyz

Hi useRs,
I'm trying for the first time to use a sem. The model finally runs,
but gives a warning saying :
"In sem.default(ram = ram, S = S, N = N, param.names = pars, var.names
= vars, : Could not compute QR decomposition of Hessian.
Optimization probably did not converge. "

Dear all,
I have run into a problem when running some code implemented in the
Bioconductor panp-package (applied to my own expression data), whereby gene
expression values of known true negative probesets (x) are interpolated onto
present/absent p-values (y) between 0 and 1 using the *approxfun -
Hi
well, I will add some explanation

Take a look at pretty function.

So it stays a zoo object with the same index. We are only replacing
the data part.

Hi
This is probably more of a statistics question than a specific R
question, although I will be using R and need to know how to solve the
problem in R.
I have several sets of data (ejection fraction measurements) taken in
various ways from the same set of (~400) patients (so it is paired data).

I'll try them,
Why do you use the brackets in zz[] ?

thanks, the lower.tri idea is I guess the best way. Will try that.
