Hi,
You can also try this:
sapply(lapply(splitlist,rle),`[[`,2)[1,]
#[1] "a1" "a2"
sapply(lapply(splitlist,rle),`[[`,2)[2,]
#[1] "b1" "b2"
A.K.

Subject: [R] splitting character vectors into multiple vectors using strsplit
Hi folks,
Suppose I create the character vector charvec by
> charvec<-c("a1.b1","a2.b2")
> charvec
[1] "a1.b1" "a2.b2"
and then I use strsplit on charvec as follows:
> splitlist<-strsplit(charvec,split=".",fixed=TRUE)
> splitlist
[[1]]
[1] "a1" "b1"
[[2]]
[1] "a2" "b2"
I was wondering whether there is already a function which can extract
the "a" and "b" parts of the list splitlist; that is, that can return
the same vectors as those created by c("a1","a2") and c("b1","b2").
Thanks,
David Romano
