[Rd] Not all functions work in RSPerl package? (PR#9242)

[xianjun.dong at bccs.uib.no]

Hi, 

It looks that not all function in R could be implemented by RSPerl. For
example,  when I call

&R::callWithNames("boxplot", {'', at y1});
or
R::barplot(\@y1);

There would be error:

Error in -0.01 * height : non-numeric argument to binary operator
Caught error in R::call()

The same happened when calling "barplot", but it's ok to call plot.

Is it a bug?
