Hello Friedrich,
thanks for your help and it is really not important that the solution
is elegant. Important is only that there is a solution.
But I still have some problems with this topic.
#I tried as you suggested to order the vectors separately. My first
problem is that my data is a data.frame:
data.frame': 348 obs. of 1 variable:
$ bracts.length.relative.to.flower...............Min: Factor w/ 4
levels "1","2","3","4": 2 3 3 3 3 2 1 4 3 2 ...
bracts.length.relative.to.flower...............Min
1 2
2 3
3 3
4 3
5 3
6 2
#I tried to convert it to a vector using this:
bract.awnMin<-as.vector(bract.awnMin)
'#and then to use sort.list:
sort.list(bract.awnMin)
Fehler in sort.list(bract.awnMin) :
'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?
#if I try to use the following for the data.frame with two variables,
it works well.
bract.awn[order(bract.awn[,1]),]
#but I have tu order both variables an therefore I should do that
separately and then use cbind.
Can somebody help me with my problem please?
Greetings
Birgit
