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
Dear ALL:
How I can find the number of observations less than each value in column one
with indicator 1 in column two. Please see the data below.
For example: number of observations less than 1 with indicator 1 (including
those 1 with indicator 1) =2
number of observations
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))

Dear ALL:
I have two quick questions about how to perform some steps in R. Could you
please see the attached MS file if the data not clean enough in this email.
Thank you so much for all your helps.
