c
static method c : R::NDArray::Time::Piece ($data : object of Time::Piece|Time::Piece[]|R::NDArray::Time::Piece|string|string[]|R::NDArray::String, $dim : int[] = undef);
Creates a new R::NDArray::Time::Piece object given the data $data and the dimensions $dim.
Implemetation:
If $data is defined and the type of $data is Time::Piece, $data is set to [(Time::Piece)$data].
If $data is defined and the type of $data is R::NDArray::Time::Piece, $dim is set to $data->(R::NDArray::Time::Piece)->dim unless $dim is defined and $data is set to $data->(R::NDArray::Time::Piece)->data.
If $data is defined and the type of $data is string, $data is set to R::OP::String->c($data)->to_time_piece_ndarray->data.
If $data is defined and the type of $data is string[], $data is set to the return value of R::OP::String->c($data)->to_time_piece_ndarray->data.
If $data is defined and the type of $data is R::NDArray::String, $dim is set to $data->(R::NDArray::String)->dim unless $dim is defined and $data is set to $data->(R::NDArray::String)->to_time_piece_ndarray->data.
And this method calls R::NDArray::Time::Piece#new method given $dim and $data.
Exceptions:
The type of the data $data must be Time::Piece, Time::Piece[], R::NDArray::Time::Piece, string, string[], R::NDArray::String if defined. Othrewise, an exception is thrown.
eq
static method eq : R::NDArray::Int ($x_ndarray : R::NDArray::Time::Piece, $y_ndarray : R::NDArray::Time::Piece);
Creates a new R::NDArray::Int object of the same dimensions as the n-dimensional array $x_ndarray for a return value, performs the comparison logic $x_ndarray->elem_cmp($x_ndarray->data, $i, $y_ndarray->data, $i) == 0 on the each element(the index is $i) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
ne
static method ne : R::NDArray::Int ($x_ndarray : R::NDArray::Time::Piece, $y_ndarray : R::NDArray::Time::Piece);

Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.

Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.

Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
lt
static method lt : R::NDArray::Int ($x_ndarray : R::NDArray::Time::Piece, $y_ndarray : R::NDArray::Time::Piece);
Creates a new R::NDArray::Int object of the same dimensions as the n-dimensional array $x_ndarray for a return value, performs the comparison logic $x_ndarray->elem_cmp($x_ndarray->data, $i, $y_ndarray->data, $i) < 0 on the each element(the index is $i) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
le
static method le : R::NDArray::Int ($x_ndarray : R::NDArray::Time::Piece, $y_ndarray : R::NDArray::Time::Piece);
Creates a new R::NDArray::Int object of the same dimensions as the n-dimensional array $x_ndarray for a return value, performs the comparison logic $x_ndarray->elem_cmp($x_ndarray->data, $i, $y_ndarray->data, $i) <= 0 on the each element(the index is $i) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
rep
static method rep : R::NDArray::Time::Piece ($x_ndarray : R::NDArray::Time::Piece, $times : int);
Same as R::OP#rep method, but the return type is different.
rep_length
static method rep_length : R::NDArray::Time::Piece ($x_ndarray : R::NDArray::Time::Piece, $length : int);
Same as R::OP#rep_length method, but the return type is different.
