Hello Vincent,
I am a beginner in using R so my question could seem very simple. I would
like to download the package multiv to do multivariate data analysis. The
package I download seems to be a file meant for UNIX and I am using a Window
OS. How could I download and install correctly this

Please accept my apologies...it turns out that my occasional mode of copying

Depending on what you mean (same x-axis and y-axis), look at
?points or ?lines OR (same x-axis, different y-axes) plot(...);
par(new=TRUE); plot(...,ann=FALSE). (The latter is asked frequently on
this list.)

Hi,
Dear Help List,
My name is Matt Oliver. I have been using R for about a year and find it very
helpful. However, I have a need for a function that I cannot find. I am not very
good at programming so I thought I would ask the group.
I have an irregular grid of data (x = Longitude, y = Latitude).
If your system is set up appropriately, you should be able to use the menu

Hi,
I am a grad student at the university of Louisiana at Lafayette. I have a
question. I have an equation with 3 unknowns. f= P/ (r+p) pow(B). I have values
of f for different r's. Can i use R to find the P,p,B values which are
constants. The equation is Manderbolts equation.
Thanks

Hi,
I am trying to install R on Windows. I copied the set
up binary. But it is corrupted on all the mirror
sites.
Thanks, that did the trick. My mclgen function can be written as
mclgen - function (datamat,catvar) {
ncat - nlevels(catvar)
perschoice-as.data.frame(rep(datamat,ncat))
perschoice-reshape(perschoice,direction=long,
varying=lapply(names(datamat),rep,ncat),

Its possible to corrupt the binary if you actually open it in a browser,
and the browser tries to display it, and then you save it.
Have you tried right-clicking on the link to download it?

What do you mean by double exponential? Can you give us another more
familiar name (e.g. Laplacian), or a reference, or a more detailed
description, or a formula for the cumulative or probability density
function?

I'm using R to create a trellis plot using the library of Pinheiro Bates

The scales argument of lattice plots achieve this.
For instance you could have
xyplot(y ~ x, data=my.data, scales=list(x=list(at=c(0, 0.1, 0.2),
labels=c(0.0, 0.1, 0.2
Check out ?xyplot for a lot more detail on this
and other arguments to lattice functions.
Hey, All
Now I have a data set which is n-dimensional.
And want to plot the Scatter Plot Matrix which
is n by n.
Does R have such function to achieve this?
Thanks for your point.
