I believe I wrote too hastily and that what you want is sum(X < 1) which
will sum the indicator (T/F) function.

Dear ALL:


Please see below. I hope this will make it more clear.

[1,]    1    1

indicator 1 (including those 1 with indicator 1  but not 1 with
indicator 0)=2

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
