View source: R/flip.lim.R

Description

Gives a negative of the intervals of a lim object

Usage

1
flip.lim(lim = NULL, l = NULL, r = NULL, b = "[]", xlim = NA)

Arguments

lim

an object convertible into a lim object: either a vector of length 2 or a list of n left (1st element) and n right (2ndt element) interval limits

l

a vector of n left interval limits

r

a vector of n right interval limits

b

a character vector for the interval boundaries rules: "[]" (or "closed") to include both boundaries points, "][" (or "()" and "open") to exclude both boundary points, "[[" (or "[)","right-open" and"left-closed") to include only the left boundary point, and "]]" (or "(]", "left-open", "right-closed") to include only the right boundary point. The notation is simplified to "[]", "[[", "]]" and "][" only.

xlim

the minimum and maximum of the new lim object (minimum and maximum of the old one if NA; is the default)

Value

a lim object of intervals in between the provided intervals
