use Rstats;

# Vector
my $v1 = c(1, 2, 3);
my $v2 = c(3, 4, 5);

my $v3 = $v1 + v2;
print $v3;

# Sequence m:n
my $v1 = C('1:3');

# Matrix
my $m1 = matrix(C('1:12'), 4, 3);

# Array
my $a1 = array(C(1:24), c(4, 3, 2));

# Complex
my $z1 = 1 + 2 * i;
my $z2 = 3 + 4 * i;
my $z3 = $z1 * $z2;

# Special value
my $true = TRUE;
my $false = FALSE;
my $na = NA;
my $nan = NaN;
my $inf = Inf;
my $null = NULL;

# all methods is called from r
my $x1 = r->sum(c(1, 2, 3));

# Register function
r->function(my_sum => sub {
  my ($self, $x1) = @_;
  
  my $total = 0;
  for my $value ($x1->values) {
    $total += $value;
  }
  
  return c($total);
});
my $x2 = r->my_sum(c(1, 2, 3));
