dear friends,
I have a vector of clusters of TRUE and FALSE like
c(TRUE,TRUE,TRUE...,FALSE,FALSE,FALSE,TRUE,TRUE...) and want to make
that into a vector
of c(1,1,1,1...2,2,2,2,.3,3,3,3) increasing the number assigned to each
cluster as they change.
How would I do that ?
Best wishes

Try:
x - c(TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,TRUE,TRUE)
tmp - rle(x)
tmp$values - seq(along=tmp$lengths)
new.x - inverse.rle(tmp)
new.x
