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
number of all observations less than 2 with indicator 1 (including those 2 with
indicator 1 but not 2 with indicator 0) =11
number of all observations less than 5 with indicator 1 (including those 5
with indicator 1 but not 5 with indicator 0) =33
number of all observations less than 10 with indicator 1 (including those 10
with indicator 1 but not 10 with indicator 0) =43
number of all observations less than 15 with indicator 1 (including those 15
with indicator 1 but not 15 with indicator 0) =46
(1, 2,5,10,15) are the values in column one with indicator 1 in column two.
which means I need to create a vector(2,11,33,43,46) for the data in column one.

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 less than 2 with indicator 1
(including those 2 with indicator 1) =11
number of observations less than 5 with indicator 1
(including those 5 with indicator 1) =33
number of observations less than 10 with indicator
1 (including those 10 with indicator 1) =43
number of observations less than 15 with indicator
1 (including those 15 with indicator 1) =46
(1, 2,5,10,15) are the values in column one with indicator 1 in column
two.
which means I need to create a vector(2,11,33,43,46) for the data in
column one.
With many thanks.
Abou
Here is the data:
