[Rd] problem with The R/Splus--Perl Interface

I'm new to using the R/Splus--Perl Interface, and I have same problem to understand how to pass the structure from Perl to R. I'm trying to call the function 'max' on the bi-dimensional array, before I tried to do the same thing on the vector as follows:

@x = &R::call("seq", 1,10);


print "val $val \n";
and it works, after this I try to do the same things on the matrix as follows:

'create matrix x'

it's dosen't works and return me this error: invalid 'type' (list) of argument
Caught error in R::call()

After This I tried also to create a matrix from the perl code with the command call ('matrix'....) as follows:
'create array t'
my @v=&R::call("matrix",\@t,2,3);
my @v=&R::eval("matrix(@t,2,3)");
But doesn't work.

At the end my question is: there is a mode to pass a matrix from perl to R, and if it dosen't exist, how can I call a R function with an bi- dimensional array created in Perl script using the The R/Splus--Perl Interface?
