[R] Formatting with strings

[arun]

Hi,
 
You could try:
Lines1 <- readLines(textConnection("---CLUSTER 1 ---
3
4
5
6
---CLUSTER 2 ---
9
10
8
11"))
indx <- grepl("CLUSTER", Lines1)
res <- data.frame(Object=Lines1[!indx], Cluster=
as.numeric(as.character(factor(cumsum(indx)[-which(indx)], labels=gsub("\\D+","",Lines1[indx])))))

res

A.K.

Subject: [R] Formatting with strings

Dear all, I have object where I stored clusters in the following manner:

---CLUSTER 1 ---
3
4
5
6
---CLUSTER 2 ---
9
10
8
11

Now want to format the data in the following way:

Object  Cluster
3            1
4            1
5            1
6            1
9            2
10          2
8            2
11          2


How can I do this in R?

Thanks

Nico
