Nested R-expressions in r..eal

Hi all,

I have a question regarding the r..eal package for R-integration in
SWI-Prolog. Is it possible (and if so how) to nest R expressions in R
expressions.

In [1] I would like to specify the margin parameter so that the label of
the Y-axis does not interfere with the value labels of that axis.
~~~
[1]   <- barplot(Bars, par(mar=[5,5,1,1]), ylab=+Y_Axis)
[2]   <-barplot(Bars, "par(mai=c(1,1,1,1))", ylab=+Y_Axis)
~~~

The problem that I experience is that [2] works, but [1] does not. Any
ideas on this?

Btw, for those who have used the older R
interface<http://www.swi-prolog.org/pldoc/package/R.html>in the past,
I have found r..eal to be a significant improvement over that
one (link to paper on
r..eal<http://bioinformatics.nki.nl/~nicos/pbs/padl2013-real.pdf>
).

Cheers!,
