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

Description

All functions start a pseudo PostScript or Acrobat preview device, using postscript or pdf, and further registering the file name for subsequent calls to ps.end.

Usage

pdf.do(file, width = -1, height = -1, onefile = FALSE, title = NULL, ...)
pdf.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), ...)
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/PDF 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(..) or pdf(..), most probably to be left alone.

title

PostScript/PDF (not plot!) title passed to postscript() or pdf(); 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 cannot print

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() or pdf.do() from ps.latex / pdf.latex and to ps.options

Details

ps.latex and pdf.latex have an additional flavor, and just differ by some extra par settings from the *.do siblings: E.g., 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).
