[R] add cex.axis =1.2 to qqunif.plot from lattice library

[Deepayan Sarkar]

In addition to what Rolf said, a relatively obscure but generally
useful way to "globally" control fontsize is to set the underlying
grid parameter (see ?grid::gpar). The easiest way to do this is
through the lattice settings, e.g.,

lattice.options(default.theme = list(grid.pars = list(cex = 1.5)))

This is particularly useful for high resolution PNG plots for
inclusion in HTML output via knitr.
