Apologies,it should be ans<-cumsum(vec1)

I don't have access to R so I can't test my example but I think this will work.
vec ( as defined by you)
# flip the false and the trues
vec1<-ifelse(vec==FALSE,TRUE,FALSE)
ans<-cumsum(vec)

I think you can use the cumsum function. If you think of your falses
to 1 and your trues to 0 then you're just sequentially adding the
numbers in the vector.
x = c(FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, FALSE, FALSE)
y = rep(1,length(x))*(1-x)
cumsum(y)
Hope that helps,

try this:
vec <- c(FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, FALSE, FALSE)
cumsum(!vec)
I hope it helps.
Best,

Hello!
If I have a vector vec <- c(FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, FALSE
FALSE)
I can I create the following order of numbers based on vector vec:
1, 2, 2, 3, 3, 3, 4, 5
Whenever there is a FALSE I increase the number (starting with 1).
Whenever there is a TRUE I set the same number as t
6 matches
