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,
Mag. Ferri Leberl
-------------- n?chster Teil --------------
#Programm zur Erstellung eines Wasserwegenetzplanes
#St??dte
#TLD.Stadtk??rzel<-c("Stadtname",??Breite,'Breite,??L??nge,'L??nge)
de.dd<-c("Dresden",51,2,13,44)
save.image("~/gmx/allalei/kanal/kanal.RData")
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?
> de.dd
[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.

What is the problem you are trying to solve?
Meant to say coerced to "character". See "?c" On Dec 9, 2007 6:14 AM, Mag.

Thank you, this seems promissing. How can I address then a certain element e.g. to add the second and the third component? Faithfully, Mag.

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,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 $b [1] 1 2 3 4 $c [1] "this is a string" $d $d[[1]] [1] 1 $d[[2]] [1] 2 $d[[3]] [1] 3> my.list$a[,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9> my.list$d[[1]] [1] 1 [[2]] [1] 2 [[3]] [1] 3> my.list$d[[2]][1] 2> my.list[[4]][[2]] # same as above[1] 2> my.list[[1]] # same as my.list$a[,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9>On Dec 9, 2007 1:36 PM, Mag.
