Clip lines so they don't run into a set of boxes.

Description

Clip lines so they don't run into a set of boxes. Useful for labeling isolines, as it allows removal of line segments that would run into any text labels.

Usage

clip_lines(x, y, id, clip_boxes, asp = 1)

Arguments

x	Numeric vector of x coordinates
y	Numeric vector of y coordinates
id	Integer vector of id numbers indicating which lines are connected
clip_boxes	Data frame specifying the locations of boxes to clip to. Should have five columns, named x, y, width, height, theta, which specify the x and y positions of each box midpoint, as well as the box width, box height, and box angle in radians. Each box is specified by one data row.
asp	Aspect ratio (width/height) of the target canvas. This is used to convert widths to heights and vice versa for rotated boxes
