Manipulation of data.frame into an array
Hello everyone,
I want to transform a data.frame into an array (lets call it mydata), where: mydata[[1]] is the first imputed dataset...and for each mydata[[d]], the first p columns are covariates X, and the last one is the outcome Y.
Lets assume a simple data.frame:
Imputed = data.frame( X1 = c(1,2,1,2,1,2,1,2, 1,2,1,2,1,2,1,2),
X2 =

install a package from CRAN
Hi,
I've tried to install package "tseries" on my computer (on Windows) but it
doesn't work so far. I have Perl but no compilers (C or Fortran) installed.
So could anyone who happens to have them please mail me the binaries?
Many thanks in advance,

A sample question
Hello.
Given a vector 1 3 4 2 8 9 5
I want to obtain a vector with all 0 except in the second position and in
the fifth, where the numbers are the same of the first vector.
The new vector must be
0 3 0 0 8 0 0
Thank you very much.
Excuseme but my mind is out of order.

Greek in text()
I have gone over the examples and can't figure this out:
rho<-.77
text(x=.05,y=.5,paste(expression(rho),rho))
I was hoping to get this to print a Greek rho with 0.77 beside it.
Instead I get: rho 0.77 (i.e. Roman lettering)
The help on expression() is quite opaque so I don't understand how it
works.
Thanks for any help.

Using Object's Name in Function
Hi,
Suppose I have a function:
myfunc <- function(x, y) {
...
}
And within the function I want to print out the name of the x, y
vectors. For example, if I do:
> myfunc(foo, goo)
[1] "foo" "goo"
It shall return "foo", "goo" (with or without quotes is fine), where foo
and goo are two vectors with numbers.
I know this sounds strange, but I'd

function sort.list()
Derar R-people
I have troubles understanding what the function sort.list() is doing. On
the homepage it says that it returns a permutation which rearranges a
vector into ascending or descending order (like order() but on a vector
instead of a sequence).
> sort.list(c(0, 2, 10, 11, 4))
[1] 1 2 5 3 4
which does not make sense to me.
In fact I am getting the same (non-sensical) result using

Putting obejct into Graph title
Hello all -
If I want to put mean value of a matrix into the title or subtitle of a graph, how would I do this? For example, in a set of commands like below,

> gplot (m, thresh=m.mean)
> title (main="A2. Block Density of Matrix m\nplotted based on MDS",
+ sub="lines below mean density (**0.435**) suppressed")

Inputting Co-ordinates
Hello
I am trying to input some co-ordinate sets into R of the form x,y by using
lists. The command I am using is:
p1 <- list(x=c(3445,563,646), y=c(234,567,456))
However the actual co-ordinate sets that I am trying to input have 305
points each and I think that the program will not accept a command that is
as long as necessary. Is this so? If this is the case can you tell me how

Multidimensional scaling
A student of mine wants to use R to do some nonmetric multidimensional
scaling. According to the R FAQ, there's a package called pcurve that
computes multidimensional scaling solutions, but I was not able to locate
it the contrib page (I am a Windows user with R version 1.4.1). Can
anyone tell me whether it is possible to do nonmetric multidimensional
scaling with R, and if so, how?

union of lists
Hi there,
Given 2 lists of integer vectors, i.e.:
> lista1
$"1"
[1] 1 34 5
$"2"
[1] 2 1
$"3"
[1] 3 10 15
> lista2
$"1"
[1] 1 5
$"2"
[1] 2 1
$"3"
[1] 3 10 29
I want to obtain the union of both, defined
as the union of the vectors, that is

drawing ellipses

First I want to thank all the people who answered my question about line
width in graphs. I promise I will learn the 'par' help page by heart for
the end of the month !
I now want to trace some ellipses to emphasize groups of data. I found how
to trace circles with 'symbols()', but no ellipse. I'm planning on writing
