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

Creates a new R::NDArray::AnyObject given the options $options and returns it.

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

Instance Methods

create_default_data

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

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

The default data is created by the following code.

  my $default_data = new object[$length];

Exceptions:

The length $length must be more than or equal to 0. Otherwise an exception is thrown.

elem_to_string

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

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

The string is created by the following code.

  my $string = (string)undef;
  eval { $string = $elem->(Stringable)->to_string; }

elem_assign

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

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

The clone is created by the following code:

  $dist_data->[$dist_data_index] = $src_data->[$src_data_index]->(Cloneable)->clone;

elem_is_na

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

Checks if an element represets NA.

If the element $data at index $data_index is not defined, returns 1, otherwise returns 0.

clone

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

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