p.scales

Conversion between plotting scales: usr, cm, symbol


Description

Give scale conversion factors of three coordinate systems in use for traditional R graphics: use, cm, symbol.

Usage

p.scales(unit = relsysize * 2.54 * min(pin), relsysize = 0.05)

Arguments

unit

length of unit (or x and y units) of symbol coordinates in cm.

relsysize

same, as a proportion of the plotting area.

Value

A numeric 2x2 matrix, with rows named x and y, and columns, named "sy2usr" and "usr2cm" which give the scale conversion factors from ‘symbol’ (as given) to ‘usr’ coordinates and from these to ‘cm’, respectively.
