Added section on default function parameters.

Addressed #418

You rock. I just glanced at it and I think a "Best Practice" is to only add questions at the end (so that references aka 'R FAQ 7.31' remain fixed). Shall we move it and make 3.12 instead of a new 3.1 ?

@eddelbuettel I added one more change to deal with switching the verbatim environment used within the MacOS compiler flag section to the highlight code.

Nice one!

[eddelbuettel]

You never typeset this one, did you? Fix coming shortly ...

Now in b93dee8.

For what it is worth, here is a helper script I use on the Rnw files:

#!/usr/bin/Rscript

## use given argument(s) as target files, or else default to .Rnw files in directory
files <- if (length(commandArgs(TRUE)) == 0) dir(pattern="*.Rnw") else commandArgs(TRUE)

## convert all files from Rnw to pdf using the highlight driver
invisible(sapply(files, function(srcfile) {
    Sweave(srcfile, driver=highlight::HighlightWeaveLatex(boxes=TRUE))
    tools::texi2pdf(gsub(".Rnw", ".tex", srcfile))
    tools::texi2pdf(gsub(".Rnw", ".tex", srcfile), texi2dvi="pdflatex")
}))

@eddelbuettel thanks for the script. I've added it:

Good. I just expanded the intro paragraph ever so slightly.
