##### Where is the Min() or Max() or first TRUE or FALSE ?

Determines the location, i.e., index of the (first) minimum or maximum of a numeric (or logical) vector.

For a logical vector x, which.min(x) and which.max(x) return the index of the first FALSE or TRUE, respectively.

##### Usage
which.min(x)
which.max(x)
##### Arguments
x
numeric (integer or double) vector, whose min or max is searched for.
##### Value

Missing and NaN values are discarded.an integer of length 1 or 0 (iff x has no non-NAs), giving the index of the first minimum or maximum respectively of x.If this extremum is unique (or empty), the results are the same as (but more efficient than) which(x == min(x)) or which(x == max(x)) respectively.

which, max.col, max, etc.

Use arrayInd(), if you need array/matrix indices instead of 1D vector ones.

##### Examples
library(base) x <- c(1:4, 0:5, 11) which.min(x) which.max(x) ## it *does* work with NA's present, by discarding them: presidents[1:30] range(presidents, na.rm = TRUE) which.min(presidents) # 28 which.max(presidents) # 2 ## Find the first occurrence, i.e. the first TRUE: x <- rpois(10000, lambda = 10); x[sample.int(50, 20)] <- NA ## where is the first value >= 20 ? which.max(x >= 20)
