Compute the "resolution" of a data vector.
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.
resolution(x, zero = TRUE)
- numeric vector
- should a zero value be automatically included in the computation of resolution
If x is an integer vector, then it is assumed to represent a discrete variable, and the resolution is 1.
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
