Hi,
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);
$val=&R::call("max", at x);
print "val $val \n";
and it works, after this I try to do the same things on the matrix as
follows:
'create matrix x'
$val=&R::call("max", at t);
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);
or
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?
