Find the closest value(s) of a number in a vector x. Multiple values will be reported, if the differences are the same.

Closest(x, a, which = FALSE, na.rm = FALSE)

Arguments

x

the vector to be searched in

a

the reference value

which

a logical value defining if the index position or the value should be returned. By default will the value be returned.

na.rm

Closest(x, 6, which=TRUE)
#>      [,1]
#> [1,]    2
#> [2,]    4
#> [3,]    6


Closest(c(2, 3, 4, 5), 3.5)
