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, discrete = FALSE)
Arguments
- x
numeric vector
- zero
should a zero value be automatically included in the
computation of resolution
- discrete
should vectors mapped with a discrete scale be treated as
having a resolution of 1?
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
