A quick question from a social scientist new to R -
how do I get coordProj / plot.Mclust to label the
nodes by row names? Using "identify " only gives me the
row numbers... Thanks.
Greetings!
I am using prop.test to compare 4 proportions to find out whether they
are equal. According to the help function you can not have confidence
intervals if you compare more than 2 proportioI 'm working on Windoze XP and have for some time installed R in D \R and

You might also take a look at ?Anova (or ?Manova) in the car package the
last examples are for a repeated-measures ANOVA using both MANOVA and

I 'm new to R and I cannot find a simple answer to a simple question.
If I have a character vector like v <- c( '1/50 '1/2 ' '1/8 '...) how can
I convert it to a numeric vector like vn <- c(0.
My task is to create an object class for triangles. I have made a function
triangle <- function(a b gamma) {

beta <- (acos((a^2+c^2-b^2)/(2*a*c)))/pi*180

When I was using cv.lm(DAAG) I found there might be something wrong with
it. The problem is that we can 't use it to deal with a linear model with
more than one predictor variable. But I have Windows XP machines with different software configurations.

On both machines PI 'm interested in writing some model selection functions (for linear
