Dear Martin,
The plot you refer to is a scree plot.
One option (there are many) is to have a look at the nFactors package.
Despite its package description, it includes the function plotnScree.
You will find it helpful to search google for "scree plot R" and/or
use rseek.org as there are many pos

One more question Jim.
What if the names of the columns are not a combination of a letter and an
integer? Suppose they are just "names" of craniometric characteristics, like
"nasal length", "orbital width" etc?
Thanks for you reply.

This is about 'a' DCOM server. You haven't told us which (there are at
least two possibilities), but if it is the one by Thomas Baier it has its
own mailing list. This is not an R issue (and I suspect not a MATLAB one
either), so please try to use an accurate subject line.

Hi everyone
I have a matrix (let's say that it contains the values of elevation) and
want to plot its values on a map using a function such as image.plot or

I think one of the other solutions suggested a way of doing it if
"AGE" was one of the columns and you wanted to plot against all the
others. It would probably be done in this fashion:
for (i in names(df)[!(names(df) %in% "AGE")]){
plot(df$AGE, df[[i]], main=i, type='l')
}

Yes, the file will be created in the current working directory and is probably
the reason for the error in 'dbInit'. This is a bit of a dumbo on my
part---thanks for copying me.

There are several mistakes:
Why are you using only p[1], p[2]?
Afterwards you try (for i in 1:10) p[i] so you should go to p[10]?
Then you should make a pnew wich holds 10 values, so pnew[i]
This should get you back on track

Dear R users/gurus,
I have recently installed Ubuntu 7.10 (Gutsy) on my Dell Latitude D520.
First time for me, as I have always used Fedora.
R installation using "apt" has proceeded fine, both for r-base and r-base-dev.
Next, I need to install various other packages, "rgl" being first in the line

If the only reason you are writing it out is just to read it back in later
rather than writing it out as a text file use save() and load().

One way that is not absolutely direct but which works
nicely is the xtable package.
Yes. It gives me exactly the same problems.
In fact I have tried the pre-built first and then the source, hoping it would,
