A ggplot2 theme that matches the defaults of the factorial figures in the package PTCA4CATA

Description

theme_ptca2: A ggplot2 theme that matches the defaults of the factorial figures in PTCA4CATA. theme_ptca2 is, obviously, a (slightly smarter) cousin of PTCA4CATA::theme_ptca (which will be deprecated in the near future).

Usage

theme_ptca2(mire = TRUE, x0 = 0, y0 = 0, coor.fixed = TRUE, base_family = "")

Arguments

mire	(Default = TRUE) when TRUE plot the factorial axis at values x0 and y0.
x0	(Default = 0) the X-axis origin. Relevant only when mire = TRUE.
y0	(Default = 0) the Y-axis origin. Relevant only when mire = TRUE.
coor.fixed	(Default = TRUE), when TRUE the X and Y axis have the same units, when FALSE the units are set by ggplot2, if a number is provided it will give the aspect ratio (i.e., Y/X) to be used to plot the graph..
base_family	the font family for the text (e.g., on a mac 'Times', 'Arial', 'Courier', 'Symbol', or plain R, 'sans', 'serif', 'mono', can also be other fonts if installed). Default is "" (i.e., theme_ptca2 uses the current default font family).
