Working with ranges of a list
Thank you for the attempt.
On your advice I am working with lists to avoid the numbers (which are
geographical coordinates) becoming strings. The call you suggest does
not take care of that. Now I am trying to extract the coordinates from
the list efficiently. Of course I could make a loop, e.g.
punkte[,1]<-orte[[1]][[2[1]]]
being replaced by
for(n in 1:lang){
punkte[n,1]<-orte[[n]][[2[1]]]
punkte[n,2]<-orte[[n]][[3[1]]]
}
but I wonder if there was no more efficient way.
Faithfully,

Is this what you want as output:
do.call('rbind', kaste)
[,1] [,2] [,3] [1,] "Bremerhaven" 53.55 8.58 [2,] "Cuxhaven" 53.87 8.7 [3,] "L??beck" 53.87 10.69 On Dec 16, 2007 8:54 AM, Mag. Ferri Leberl <ferri.leberl at gmx.at> wrote:
Dear everybody!
Please find attached a tiny R-program. It returns:
[,1] [,2]
[1,] 53.55 NA
[2,] 53.55 NA
[3,] 53.55 NA
How can I manage the first column to show the second component not only
of the first list in k?ste but of the second component of every list in
k?ste respectively, such as to get the following array returned:
[,1] [,2]
[1,] 53.55 NA
[2,] 53.87 NA
[3,] 53.87 NA
Thank you in advance.
