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" "51" "2" "13" "44"
de.dd<-list("Dresden",51,2,13,44)
de.dd
[[1]]
[1] "Dresden"
[[2]]
[1] 51
[[3]]
[1] 2
[[4]]
[1] 13
[[5]]
[1] 44
A list will maintain the mode of each element.

Dear Everybody,
Enclosed are the tiny beginning of a program and its output.
As a pity, if I load the image <load("kanal.RData")> the elements of
<de.dd> are non numerical; <de.dd[2]+de.dd[3]> returns <Fehler in
de.dd[2] + de.dd[3] : nicht-numerisches Argument f?r bin?ren Operator>.
How can I keep the numbers numerical?
Thank you in advance.
hopefully,
