resolution: Compute the "resolution" of a numeric vector
Description
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.
Usage
resolution(x, zero = TRUE)
Arguments
x
numeric vector
zero
should a zero value be automatically included in the
computation of resolution
