resolution: Compute the "resolution" of a data vector.

In rpruim/ggvis2: Interactive grammar of graphics

Description

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