  Can someone please help me what's the below code means (I have a very
  vague idea)  and where I can get some information on these commands

  cex=1.4),

  > superpanel=panel.pairs.hh, subpanel.scales=list(cex=.5),

  > cex=.7, panel.cex=1)

These are obtions to lattice plots, and there is nothing 'finance'-specific
about them. See

as a start.

is also a good idea.  More specifically, the code above seems to set pairs
plots for each of the panels in a lattice plot, with specific option for
fonts size (cex does that).

Hope that helps, Dirk
