Question

I have a variable (Var) which stores 10000 values and is of integer nature.

I want to count, how many times 1000 or higher than 1000 numeric value occurs in this list.

Any one liner in R?

Thank you in advance.

Answer 1

sum(Var >= 1000) will do it, as long as Var is a vector. If not, you’ll need to tell R to find Var inside whatever object contains it. Here is an example:

> set.seed(2)
> Var <- sample(900:1100, 10)
> Var
 [1]  937 1040 1014  933 1085 1084  925 1061  990 1005
> Var >= 1000
 [1] FALSE  TRUE  TRUE FALSE  TRUE  TRUE FALSE  TRUE FALSE  TRUE
> sum(Var >= 1000)
[1] 6

This uses the fact that TRUE = 1 and FALSE = 0.
