`file`	Name of pdf output file.
`x, y`	x and y coordinates of points to plot.
`start, end`	x coordinates of start and end positions of regions.
`label`	Labels for regions.
`width`	Width in inches of pdf output.
`ymax`	Value to replace infinite y-coordinates with.
`transform`	Function to be applied to y-coordinates before plotting.
`col`	Color for points (defaults to black).
`main`	String used as plot title.
`upper_hook`	Function that will be called right after the upper part of the plot is created. Its arguments correspond to ‘x’, ‘y’, ‘start’, ‘end’, and ‘label’.
`lower_hook`	Same as ‘upper_hook’ except that the function is called right after the lower part of the plot is created.
`point_cex`	Factor by which points in plot are magnified.
`pch`	Character/symbol used for points (see `points`).
