i'm sorry. i tested it afterwards and of course
it had some problems. below is the working version.


myvector<-c("A","B","C","D","E")

result<- lapply(1:length(myvector), function(.length) {
myvector[1:.length]
})


print(result)

lapply(1:length(myvector) function(.length) {
c(myvector[1}:myvector[.length])
})

but test it because i didn't.

Hi all,

What may be a smart, efficient way to get the following result:

myvector <- c("A","B","C","D","E")
myseries <- miracle(myvector)
myseries
[1]
[[1]] "A"
[2]
[[1]] "A" "B"
[3]
[[1]] "A" "B"
[4]
[[1]] "A" "B" "C"
[5]
[[1]] "A" "B" "C" "D"
[6]
[[1]] "A" "B" "C" "D" "E"

Thanks for any hints,

Joh
