create suite of common statistical actors using R

Description
We need to create a suite of commonly useful analytical actors using the R actor
that is described in bug #1342. These actors should require zero 'plumbing' by
the user -- all they should need to do is hook up their data to the ports and
hit run. These will include some common operations such as means and error by
group, linear regression, anova, t-test, etc. Each of these will be described
in their own bug and linked to this bug as a blocker.
The RExpression actor has been created as the basic template for this suite of
actors. Some example exist but more need to added. Basically, the task is just
to define the port and add the appropriate R scripts. The RExpression actor
takes care of the 'plumbing' issues.
Lets attempt to get at least a handful of R statistical actors created that can
be reused. Madin can probably handle this in the context of the biodiversity
workflows he was working on. Some possibilities include:
Univariate summary stats (mean, sdev, stderr, var, n) (already checked in)
Simple parametric regression (already checked in)
Simple non-parametric regression
Simple ANOVA
Correlation (pearson, spearman)
Scatterplot, bar chart, line plot
A suite of R statistical actors is now installed in the Beta1 release
