[R] Assign numbers in R

[Kehl Dániel]

Hi,

is this homework? 
Try
d <- c(8,7,5,5,3,3,2,1,1,1)

r <- rep(1,length(d))

for (i in 2:length(d)) {
  
  if (d[i] != d[i-1]) {
    r[i]=r[i-1]+1;
  }
  else {
    r[i] = r[i-1];
  }
}

Although I am sure there are better solutions!

Tárgy: [R] Assign numbers in R

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!
