Hi,
Does anybody know whether it's possible (and sensible) to calculate R^2 (or
something approximating R^2) on the results of a major axis Model II regression

The function lmodel2 provides an R^2 for the OLS regression only (example

Yes,
I already have solid code to estimate the probabilities and gather the

What I'm stuck on is how to train the "race-wise" logit and then somehow

It really sounds like you want to use points(). Maybe I'm missing the

coordinates so passing it's output to points() should plot those

of the previous ellipse).
In the solution you cite, yes. In the second solution I provided

I didn't know that OS matters. My machine is a linux machine.
I have a few different version of R installed in my machine (different
commands like R, R-2.9.0, R-2.8 ..). But I don't see the version of
Rscript. How to figure out which version of R my Rscript uses?

That's pretty straightforward to do - here's a simple function. The
exact behavior
at the "edges" is left as an exercise. :)
rbound <- function(rmin, rmax)
{
x <- runif(1)
x <- x * (rmax - rmin) + rmin
x
}

Thanks Martin, it's clearer now.
Indeed things get a bit dirty with replace methods. I'm wondering if
it's a bug, a normal behaviour or if there is nothing to do about it?
I think it's because the replace method of A into B is not called after
replacing an object's slot. I imagine this would be
Hi,
I would obtain a random value between two (for example between 40.15 and 56.58
I would have only one value).
I'm looking for a package/a function which could do this.
Could anybody help me please?

Try something along these lines:
gsub("[^[:alnum:][:space:],]", "", string)

Dear Sir,
I am working with one example in R donlp2. How I can get the Hessian matrix
from the output.
p = c(10,10)
par.l = c(-100,-100)
par.u = c(100,100)
nlin.l = nlin.u = 2
fn = function(x) {
x[1]^2+x[2]^2
}
dfn = function(x){
c(2*x[1], 2*x[2])
}
attr(fn, "gr") = dfn
nlcon = function(x){
x
Try this:
string <- "Aaaa. , ccc"
gsub("[^,[:alpha:]|[:space:]]", "", string)

Hi,
Are there any R packages around which would break down a time series into a
MxN table for analysis purposes?
For example, show the total sales per month per calendar year.

You did not specify your OS, but you might try at the shell prompt:
Rscript file.R

Open the file in a text editor and see what you have. Check the delimiters and

Hi,
If I run the below command, it will generate a file 'file.Rout' to
save the output. But I want the output be shown in the screen
directly. I'm wondering if there is a direct way to do so.
R CMD BATCH file.R

You have two options:
1. The `BBsolve' function in the "BB" package to solve this system of 3
equations.
2. Try `nleqslv' function in the "nleqslv" package.
These would work even if the residual is not zero.
Hope this helps,
Ravi.

Try this:
m[!apply(m < 0, 1, any),]

Don't understand what this has to do with SQL, or why you're asking
for SQL solutions in an R mailing list, but here are some R
suggestions.

You can also use ggplot2:
library(ggplot2)

qplot(x,y,data= myplot,colour=I(alpha("blue",1/25)))
