Thanks!
I see, that do.call-function is used often in R-algorithms... Looking over
some extra do.call-examples seems useful. This tail-function is also new for
me.
Is there some reason to use seq(along = VECTOR) instead of 1:length(VECTOR)?

You can replace the for with lapply like this:
VECTOR <- c(0, 3, 6, 3, 11, 2, 11, 4, 3, 4, 7, 7, 6, 4, 8)
f <- function(i) unique(tail(VECTOR, length(VECTOR)-i+1))[1:5]
out <- do.call(rbind, lapply(seq(along = VECTOR), f))
na.omit(rbind(rep(NA, 5), out))
Note that a matrix with zero rows is retu
Again my example was't very clear: there were not enough same numbers in the
VECTOR.
What I need is something like this:
VECTOR<-c(0,3,6,3,11,2,11,4,3,4,7,7,6,4,8)
MATRIX<-c()
for(i in 1:length(VECTOR)){
v<-(unique(VECTOR[i:length(VECTOR)])[1:5])
MATRIX<-rbind(MATRIX,v)
}
MATRIX<
Try:
embed(VECTOR, 5)[,5:1]

Hi,
Here is a vector and the result from the embed-command:
VECTOR=c(0,3,6,3,11,2,4,3,7,6,4,5,10,2,3,5,8)
> embed(VECTOR, dimension=5)
[,1] [,2] [,3] [,4] [,5]
[1,] 113630
[2,]2 11363
[3,]42 1136
[4,]342 113
[5,]
