I guess you are looking for the number of rows satisfying the following
condition.
Assuming that you have a cutoff k = 1, 2, 5, 10, 15
1) x[i,1] < k regardless of the value of x[i,2], OR
2) x[i,1] == k and x[i,2] == 1
Here is my take on this problem. It is not elegant but it seems to do the
job.

For me is not very clear, but if I understand:
sapply(sort(unique(data[data[,2]==1,1])),
function(x)sum(data[data[,2]==1 & data[,1] <= x, 1]))
But the output is:
2 6 31 71 86

Dear Ellison:
it did not do it.
I edited my previous email to make my question more clear.
The out put should be: (2,11,33,43,46)
For example:
number of all observations less than 1 with indicator 1 (including those 1 with
indicator 1 but not 1 with indicator 0) =2
num
Try this:
data <- as.data.frame(data)
names(data) <- c('Data', 'Indicator')
a)
sort(unique(subset(data, Indicator == 1))[,1])
b) with(subset(data, Indicator == 1),
tapply(Indicator, Data, sum))
