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)numeric vector
should a zero value be automatically included in the computation of resolution
resolution(1:10)
resolution((1:10) - 0.5)
resolution((1:10) - 0.5, FALSE)
# Note the difference between numeric and integer vectors
resolution(c(2, 10, 20, 50))
resolution(c(2L, 10L, 20L, 50L))
