Hi,

I was looking for a function like "which()" but only returns the first
argument.
Compare:

x <- c(1,2,3,4,5,6)
y <- 4
which(x>y)

returns:
5,6

which(x>y)[1]
returns:
5

which(x>y)[1] is exactly what i need. I did use this but the dataset
is too big (~18 mio. Points).
That's why i need a more effective way to get the first element of a
vector which is bigger/smaller than a specific number.

I found "match()" but this function only works for equal numbers.



Thanks,
Nico
