Compute the "resolution" of a data vector.

Source: R/utilities-resolution.r
resolution.Rd

The resolution is is the smallest non-zero distance between adjacent values. If there is only one unique value, then the resolution is defined to be one.

Usage

resolution(x, zero = TRUE)

Arguments

x

numeric vector

zero

should a zero value be automatically included in the computation of resolution

Details

If x is an integer vector, then it is assumed to represent a discrete variable, and the resolution is 1.

Examples

resolution(1:10)
#> [1] 1
resolution((1:10) - 0.5)
#> [1] 0.5
resolution((1:10) - 0.5, FALSE)
#> [1] 1
resolution(c(1,2, 10, 20, 50))
#> [1] 1
resolution(as.integer(c(1, 10, 20, 50)))  # Returns 1
#> [1] 1
