Dear Yihui,
thanks a lot for your kind reply. Your solution is very elegant and
versatile.
However, there is a point that is obscure to me and I didn't manage to
fully understand them after looking at the Knitr manual and graphic manual.
The issue concerns the hook:
*knit_hooks$set(par = function(before, options, envir) {
if (before) par(mar = c(4, 4, .1, .1))
})*
why do you set par as a function?
moreover, below you write:
*par(bg=rgb(runif(1), runif(1), runif(1)))*
does this mean that* before = rgb(runif(1))*;* options = runif(1)*
and*envir = runif(1)
*?
and what does this produce? I don't understand what's going on, can you
please help me or address me to some documentation?
thanks in advance for your kind help,
f.
