rpretty

R's pretty algorithm implemented in R

R's pretty algorithm implemented in R

rpretty(dmin, dmax, m = 6, n = floor(m) - 1,
    min.n = n%/%3, shrink.sml = 0.75, high.u.bias = 1.5,
    u5.bias = 0.5 + 1.5 * high.u.bias)

`dmin`	minimum of the data range
`dmax`	maximum of the data range
`m`	number of axis labels
`n`	number of axis intervals (specify one of `m` or `n`)
`min.n`	nonnegative integer giving the minimal number of intervals. If `min.n == 0`, `pretty(.)` may return a single value.
`shrink.sml`	positive numeric by a which a default scale is shrunk in the case when `range(x)` is very small (usually 0).
`high.u.bias`	non-negative numeric, typically `> 1`. The interval unit is determined as `{1,2,5,10}` times `b`, a power of 10. Larger `high.u.bias` values favor larger units.
`u5.bias`	non-negative numeric multiplier favoring factor 5 over 2. Default and 'optimal': `u5.bias = .5 + 1.5*high.u.bias`.
