There is also the basic option of using the grid package and viewports.
You can then place the plots where you want and annotate them

    pdf(file    = paste0("01", ".pdf"),
        height  = 3.5,
        width   = 7,
        paper   = "special",
        onefile = TRUE,
        family  = "Helvetica",
        pointsize = 12,
        colormodel = "rgb")
    vpl <- viewport(x = 0.25, y = 0.5, width = 0.45, height = 0.9)
    grid.rect(gp = gpar(lty = "dashed"))

    vpr <- viewport(x = 0.75, y = 0.5, width = 0.45, height = 0.9)
    grid.rect(gp = gpar(lty = "dashed"))
    grid.circle(x = 0.6, y = 0.4, r = 0.3)

In your case you may need to have a viewport of the whole page

see  http://www.amstat.org/publications/jse/v18n3/zhou.pdf for examples

also have a look at the grid.clip function

Subject: [R] Output formatting in PDF


Can you please help me with the following output formatting:
I am planning to include 2 plots and some general description in a one-page
PDF document, such that

   - I'll leave some appropriate margin on the PDF- say, 1.5 inches
   top,right, bottom and left (will decide based on overall appearance)
   - the 2 plots are placed side-by-side (looks best for comparison)
   - the margins for each plot can be 4 lines on the top and the bottom &
    2 lines on the left and the right
   - each of these 2 plots would have time (0 to 260) along x-axis and two
   time-series (daily USD-GBP and USD-EUR FX rates) on the y-axis, i.e. 2
   time-series would be plotted on each of the 2 graphs. I would need a
   different color for each plot to demarcate them
   - I need to add some text (eg: "Independent analysis of Exchange Rate
   dynamics") with reduced font size (not high priority though-just good to
   have a different size)
   - The general discussion (may be a paragraph) would come right below the
   2 plots - I can specify this text as an argument in a function, may be. I
   am not sure how to arrange the entire PDF as per the format I mentioned

I shall really appreciate any help with this - the time series analysis is
not difficult, I can manage that - however, I don't know how to manage the
formatting part though, so that the 1-pager output looks decently
presentable. Thanks.
