Red Arrow GSL adds `Arrow::*Array#to_gsl`/`Arrow::Tensor#to_gsl` for Apache Arrow to GSL conversion. Red Arrow GSL adds `GSL::Vector#to_arrow`/`GSL::Vector::Int#to_arrow`/`GSL::Matrix::*#to_arrow` for GSL to Apache Arrow conversion.

Red Arrow NMatrix adds `Arrow::Tensor#to_nmatrix` for Apache Arrow to NMatrix conversion. Red Arrow NMatrix adds `NMatrix#to_arrow` for NMatrix to Apache Arrow conversion.

Red Arrow Numo::NArray adds `Arrow::Tensor#to_narray` and `#to_arrow`/`#to_arrow_array` to `Numo::NArray`'s numerical subclasses such as `Numo::Int8`. `Arrow::Tensor#to_narray` returns a `Numo::NArray`'s numerical subclass such as `Numo::Int8`. `#to_arrow` returns a `Arrow::Tensor`. `#to_arrow_array` returns an `Arrow::Array` instance if the original object is an 1 dimensional array.

Red Datasets Arrow adds `#to_arrow` method to each dataset in Red Datasets. You can get dataset as `Arrow::Table` object. `Arrow::Table` is provided by [Red Arrow](http://github.com/red-data-tools/red-arrow).

Red Datasets Daru adds `#to_daru` method to each dataset in Red Datasets. Using this method, you can obtain dataset as an object of `Daru::DataFrame` class, which is provided by [daru](https://github.com/sciruby/daru).

Red Datasets GDK Pixbuf adds `#to_gdk_pixbuf` method to some datasets in Red Datasets. You can get `GdkPixbuf::Pixbuf` objects from a dataset.

Red Datasets Numo::NArray adds `#to_narray` method to each dataset in Red Datasets. You can get dataset as Numo::NArray's numeric subclass object.

Red Datasets Pandas adds `#to_pandas` method to each dataset and its table in Red Datasets. You can get data as Pandas::DataFrame class object.
