Several different ways. You can look in the Intro to R to learn more:
> my.list <- list(a=matrix(1:9,3), b=1:4, c="this is a string", d=list(1,2,3))
> my.list
$a
[,1] [,2] [,3]
[1,]147
[2,]258
[3,]369
$b
[1] 1 2 3 4
$c
[1] "this is a string"
$d
$d[[1]
Thank you, this seems promissing. How can I address then a certain
element e.g. to add the second and the third component?
Faithfully,

Meant to say coerced to "character".
See "?c"

You program contains:
de.dd<-c("Dresden",51,2,13,44)
and since you are mixing characters with numerics and putting them
into a single vector, the data is coerced to a common data type, which
in this case is numeric. What are you trying to do? Do you want to
use a list?

[1] "Dresden" "5
Dear Everybody,
Enclosed are the tiny beginning of a program and its output.
As a pity, if I load the image the elements of
are non numerical; returns .
How can I keep the numbers numerical?
Thank you in advance.
hopefully,
