my $ndarray = R::NDArray::Long->new({data => [(long)1, 2, 3, 4, 5, 6], dim => [3, 2]});

Super Class

R::NDArray

Field

data

method data : long[] ();

Same as R::NDArray#data method, but the return type is different.

Class Methods

new

static method new : R::NDArray::Long ($options : object[] = undef);

Creates a new R::NDArray::Long and returns it.

This method calls R::NDArray#init method given the options $options.

Instance Methods

create_default_data

method create_default_data : long[] ($length : int = 0);

Creates a default data given the length $length and returns it.

elem_to_string

method elem_to_string : string ($data : long[], $data_index : int);

Converts an element $data at index $data_index to a string and returns it.

elem_assign

method elem_assign : void ($dist_data : long[], $dist_data_index : int, $src_data : long[], $src_data_index : int);

Assigns the element $src_data at index $src_data_index to the element $dist_data at index $dist_data_index.

elem_clone

method elem_clone : void ($dist_data : long[], $dist_data_index : int, $src_data : long[], $src_data_index : int);

Copies the element $src_data at index $src_data_indext to the element $dist_data at index $dist_data_index.

elem_cmp

method elem_cmp : int ($a_data : long[], $a_data_index : int, $b_data : long[], $b_data_index : int);

Compares the element $a_data at index $a_data_index and the element $b_data at index $b_data_index and returns the result.

method elem_is_na : int ($data : byte[], $data_index : int);

Checks if an element represets NA.

Returns 0.

clone

method clone : R::NDArray::Long ($shallow : int = 0);

Same as R::NDArray#clone method, but the return type is different.

slice

method slice : R::NDArray::Long ($asix_indexes_product : R::NDArray::Int[]);

Same as R::NDArray#slice method, but the return type is different.
