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
