Usage

Arguments

all other arguments in pretty.

Details

calculates pretty(x), then removes the values that do not lie within range(x). If force=TRUE, range(x) is reduced step by step in a while loop until the condition is met. This is useful if you want exactly 2 labels on an axis. In order not to get stuck, the outer values are taken if there are more than n values within range(x).
