Menentukan lokasi, yaitu indeks minimum atau maksimum (pertama) dari vektor numerik (atau logis).
which.min(x)
which.max(x)| Parameter | Deskripsi |
|---|---|
x |
numeric (logical, integer or double) vector or an R object for which the internal coercion to double works whose min or max is searched for. |
# NOT RUN {
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, if there is at least one:
x <- rpois(10000, lambda = 10); x[sample.int(50, 20)] <- NA
## where is the first value >= 20 ?
which.max(x >= 20)
## Also works for lists (which can be coerced to numeric vectors):
which.min(list(A = 7, pi = pi)) ## -> c(pi = 2L)
# }
