smallest and the highest value
Usage
defaultLevels(x, step = 1)
Arguments
- x
numeric or character vector
- step
step to be used in sequence generation
Value
if x is numeric the sequence between the lowest and highest
value in x with the given step is returned. If x is a
vector of character strings, the sorted unique values are returned.
Examples
defaultLevels(c(1, 3, 4, 5, 4))
#> [1] 1 2 3 4 5
defaultLevels(c(1920, 1950, 1970), step = 10)
#> [1] 1920 1930 1940 1950 1960 1970
