Hello,
I'm working with a dataset that has 2 columns and 1000 entries. Column 1 has

5.
This is my attempt, which works but doesn't seem to be

Hello,
Since logical values F/T are coded as integers 0/1, you can use this:
set.seed(5712) # make it reproducible
n - 1e3
x - data.frame(A = sample(0:1, n, TRUE), B = sample(0:10, n, TRUE))
count - sum(x$A == 1 x$B 5) # 207
Hope this helps,
