Description Usage Arguments Details Value Examples

Written in C++, this function tends to run much faster than the equivalent
(if maximum is unique) base R solution
`which(x == max(x), arr.ind = TRUE)`

.

1 | ```
which_max_im(x)
``` |

`x` |
Integer matrix. |

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

:

`which_max_nv`

for numeric vector.

`which_max_iv`

for integer vector.

`which_max_nm`

for numeric matrix.

`which_max_im`

for integer matrix.

Integer vector.

# which_max_im is typically much faster than
# which(x == max(x), arr.ind = TRUE)
x <- matrix(rpois(100, lambda = 15), ncol = 10)
all(which(x == max(x), arr.ind = TRUE) == which_max_im(x))
benchmark(which(x == max(x), arr.ind = TRUE), which_max_im(x),
replications = 5000)
