Re: [R] AIC for regression models (was: (no subject))
Yes, you can use the `AIC' function in R: > set.seed(100) > x1 <- rnorm(100) > x2 <- rnorm(100) > y <- x1 + x2 + rnorm(100) > AIC(lm(y ~ x1 + x2)) [1] 286.7287 -roger ___ UCLA Department of Statistics [EMAIL PROTECTED] http://www.stat.ucla.edu/~rpeng On Fri, 24 Jan 2003, Simon CHAMAILLE wrote: > Dear All A> I just want to know if it is easily possible to compute AICc calculation for multiple regression models under R ? > Thanks a lot, > simon chamaillé > > __ > [EMAIL PROTECTED] mailing list > http://www.stat.math.ethz.ch/mailman/listinfo/r-help > __ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] Plotting coloured histograms...
Hi, I am having some trouble trying to plot a histogram in more than one colour. What I want to do is, plot two vectors in the same histogram, but with different colours, for instance: > x <- rnorm(1000,20,4); > y <- rnorm(1000,10,2); Then I'd like to have x and y ploted on the same hist (I can do that already doing w <- c(x,y) then hist(w)) but the bars representing the x's should be in one colour and the bars representing the y should be in another one, so that I could see the overlaping areas of the two distributions etc. Is there any way to do that? I've read through the hist docummentation (>help(hist)) and also googled for "R colour histogram" but didn't find anything helpfull.

[R] survey package
A new package `survey' for analysing complex survey samples is on CRAN. It handles stratification, clustering, and unequal sampling probabilities in descriptive statistics, glms, and general maximum likelihood fitting. The package is still under development: - it doesn't do the finite population correction to variances - it needs some real life worked examples Most importantly, though, I don't do this sort of analysis routinely, so it's possible that some part of the interface is completely insane from the viewpoint of practising survey statisticians. Now would be an excellent time to complain. -thomas Thomas Lumley Asst.

Dear helpers
I have this code to make 10 plots in the same device

You mean:
split.screen(c(2, 5))
for (i in 1:10){
nova.matriz<-a*sigma+(1-a)*S
proj<-calculo.comp(treino,nova.matriz)
print(proj[,1:2])
screen(i)
plot(Re(proj[c(2,3,6,9:11,14,23),1:2]),xlim=range(c(-
15:15)),ylim=range(c(-5:5)),col="black")
points(Re(proj[c(1,4:5,7:8,12:13,15:22,24:27),1:2]),col="red")
points(Re(proj[28:38,1:2]),col="blue")
a<-a-.1
}
Is this the best way to do it? And I have this problem. It only
plots 6 screens and then gives an error
"Error in plot.new() : Figure margins too large"
The idea is to make 10 plots being a function of parameter a.
It goes from 1 to zero. I've already started at zero and gone
to 1 but it happens the same thing.
Any hints?
What about reducing the margins (the obvious idea after reading the
error message) or enlarging the space for the figures in another way
(larger device region etc.)?
In order to reduce the margins, e.g. use
...
screen(i)
par(mar=c(2,2,1,1))
...
I think you don't need such a complex thing like split.screen().
Another way is to use
par(mfrow=c(5, 2))
or see ?layout for a third way.
