Description Usage Arguments Value Examples
Returns the signed value of the element with the minimum absolute value in a vector.
1 | absolute.min(x)
|
x |
Numeric vector ( |
A single value; the value with the smallest absolute value, but with
its original sign. This is equivalent to (and implemented as)
x[which.min(abs(x))]
The value is NA
if x
has no non-NA
values
(c.f. which.min
).
1 2 3 4 5 6 7 8 9 10 11 12 | set.seed(1)
x <- rnorm(16)
min(x) # -2.2147
min(abs(x)) # 0.0444
absolute.min(x) # -0.0444: preserves sign
# NA values OK:
absolute.min(c(-1, 4, NA))
# Slightly unintuitive behaviour:
absolute.min(numeric(0)) # numeric(0)
absolute.min(NA) # NA
