Compute the "resolution" of a numeric vector

Source: R/utilities-resolution.r

The resolution is the smallest non-zero distance between adjacent values. If there is only one unique value, then the resolution is defined to be one. If x is an integer vector, then it is assumed to represent a discrete variable, and the resolution is 1.

resolution(x, zero = TRUE)

Arguments

x

numeric vector
zero

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

Examples

resolution(1:10)
#> [1] 1
resolution((1:10) - 0.5)
#> [1] 0.5
resolution((1:10) - 0.5, FALSE)
#> [1] 1

# Note the difference between numeric and integer vectors
resolution(c(2, 10, 20, 50))
#> [1] 2
resolution(c(2L, 10L, 20L, 50L))
#> [1] 1
