ps.latex: PostScript Preview Device with Optional `LaTeX' Touch

Description

Both functions start a ``Pseudo PostScript Preview'' device, using postscript, and further registering the file name for subsequent calls to ps.end.

Usage

ps.do(file, width=-1, height=-1, onefile=FALSE, horizontal=FALSE,
      title = NULL, ...)
ps.latex(file, height = 5 + main.space * 1.25,  width = 9.5,
         main.space=FALSE, lab.space = main.space,
         paper = "special", title = NULL,
         lab=c(10, 10, 7), mgp.lab=c(1.6, 0.7, 0), mar=c(4, 4, 0.9, 1.1), ...)

Arguments

file

character giving the PostScript file name to be written.

height

device height in inches, height * 2.54 are cm. The default is 5 plus 1.25 iff main.space.

width

device width in inches; for this and height, see postscript.

onefile, horizontal

logicals passed to postscript(..), most probably to be left alone.

title

PostScript (not plot!) title passed to postscript(); by default use a title with Rversion and file in it.

main.space

logical; if true, leave space for a main title (unusual for LaTeX figures!).

lab.space

logical; if true, leave space for x- and y- labels (by not subtracting from mar).

paper

character, see postscript. Only if this is "special" are your choices of width and height completely honored (and this may lead to files that can't print o

lab

integer of length 3, lab[1:2] are desired number of tick marks on x- and y- axis, see par(lab=).

mgp.lab

three decreasing numbers determining space for axis labeling, see par(mgp=), the default is here smaller than usual.

mar

four numbers, indicating marginal space, see par(mar=), the default is here smaller than usual.

...

arguments passed to ps.do() from ps.latex

Details

ps.latex has an additional flavor, and just differs by some extra par settings: After ps.do(..) is called, the graphical parameters c("mar", "mgp", "lab") are reset (to values that typically are better than the defaults for LaTeX figures).
