which_min_nv: Return Index of (First) Minimum of a Numeric Vector
In vandomed/dvmisc: Convenience Functions, Moving Window Statistics, and Graphics

Description Usage Arguments Details Value Examples

Written in C++, this function tends to run faster than which.min for large numeric vectors.

1	which_min_nv(x)

`x`	Numeric vector.

For optimal speed, choose the version of this function that matches the class of your x:

which_min_nv for numeric vector.
which_min_iv for integer vector.
which_min_nm for numeric matrix.
which_min_im for integer matrix.

Integer value.

# For long vectors, which_min_nv is faster than which.min
x <- rnorm(100000)
which.min(x) == which_min_nv(x)
benchmark(which.min(x), which_min_nv(x), replications = 1000)

# For shorter vectors, which_min_nv is slower than which.min
x <- rnorm(100)
which.min(x) == which_min_nv(x)
benchmark(which.min(x), which_min_nv(x), replications = 10000)
