which_min
From mlr3misc v0.1.0
by Michel Lang
Index of the Minimum/Maximum Value, with ties correction
Works similar to base::which.min()/base::which.max(), but corrects for ties.
Missing values are set to Inf for which_min and to -Inf for which_max().
Usage
which_min(x, ties_method = "random")which_max(x, ties_method = "random")
Arguments
- x
::
numeric()Numeric vector.- ties_method
::
character(1)Handling of ties. One of "first", "last" or "random" (default) to return the first index, the last index, or a random index of the minimum/maximum values. Passed down tobase::max.col().
Value
(integer()): Index of the minimum/maximum value.
Returns an empty integer vector for empty input vectors and vectors with no non-missing values.
Examples
# NOT RUN {
x = c(2, 3, 1, 3, 5, 1, 1)
which_min(x, ties_method = "first")
which_min(x, ties_method = "last")
which_min(x, ties_method = "random")
which_max(x)
which_max(integer(0))
which_max(NA)
which_max(c(NA, 1))
