Find the minimum of a vector ignoring certain numbers

Question

I would like to find the minimum value a of vector but without including certain value

ex :

a <- c(1, 2, 3, 4, 5 ,-9999 ,7 ,8 ,9)

And I want to avoid values 1 and -9999. So the answer here would be 2.

`min(a[!a %in% c(1, -9999)])` – josliber Apr 07 '17 at 13:49 — josliber, Apr 07 '17 at 13:49

1

We can use setdiff to include only those elements which we want and find the minimum among them.

min(setdiff(a, ignore))
#[1] 2

data

a <- c(1, 2, 3, 4, 5 ,-9999 ,7 ,8 ,9)
ignore <- c(1, -9999)
