Try the following

Thank you very much for the advice using
data.frame(I(names), ages)
I received two solutions within 15 minutes of my initial request.
What a quick and nice counterexample for the often heard claim: Free

Dear collegue,
I have some questions about lattice graphs:
1. How can I introduce different lines in different graphs, from the same
page? For example, in the upper row of graphs, I would like to have a line
at 0.5, in the middle one at 0.3, and in the lower at 0.1. I am using
panel.abline, but
3. How can I make that the symbol within the graph varies with two
variables, for example when it is good I want to put a open circle and when
it is bad a closed circle or for example, that each point gets the number
of samples..., but this changes throughtout the graphs...
It's not clear to

Hi
I am trying to replicate a vector in n rows for comparison purposes with
another matrix.
foo - c(1,2,3)
bar - rbind(foo,foo) # does the trick for 2 rows
bar - rbind(rep(foo,2)) # does something else
How do I generate a matrix with all rows=foo without writing 'foo' n times as
arg?
Thanks,
Using the recyling rule:
bar - matrix(foo, nrow=n, ncol=length(foo), byrow=TRUE)
HTH,
Andy

Dear R users,
I created a program for a simulation. It produces datasets and then it
conducts some fits with the function coxph. Sometimes this function produces
warnings, but I get only this warnings after finishing my program. Is there any
possibility to get these hints earlier, maybe at once
One way is setting the (or adding to an existing one)
environment variable LD_LIBRARY_PATH to your directory

in the R Administration/Installation manual which I'd warmly
recommend consulting here.

Hi
I get a matrix with the columns named like X13 X22 X1 X14 ..., i.e. not
successively. That has it's good reasons, but now how can I rename the
columns to X1 X2 X3 ...?
Thanks a lot,

colnames(x) - cc
where x is your matrix.
R is a vectorized language:
colnames(x) - paste(X, 1:ncol(x), sep='')
will do.

Perhaps you should read one of the introductory manuals in the Contributed
Documentation section of cran.us.r-project.org. This will introduce many
of the basic commands, and save you time and frustration.
You will probably end up wanting to use either read.table or scan to get
your data into R.

I would like to be able to add the random effect for the slope to the fitted value for

The fitted values at the population level should be the fixed effects (B_00 and B_01).
So each school should have the same fitted values,
