Hi,
Try:
 cumsum(c(TRUE,d[-1]!=d[-length(d)]))
A.K.

Hi,
I have the following numbers:

d <- c(8,7,5,5,3,3,2,1,1,1)

I want to convert these into the following numbers:

r:
1,2,3,3,4,4,5,6,6,6

So if two numbers are different increment it if they are same then assign
the same number:

r <- NULL

for (i in 1:length(d)) {

if (d[i] != d[i+1]) {
  r[i] =i+1;
}
else {
  r[i] = i;
}
}

But this is not correct. How can I solve this problem? or how can I solve
it in a different way? Thanks a lot!
