Breaking: Fixes bug where the shuffle_pairs and shuffle_members were kind of switched. Now shuffle_pairs changes the order of pairs while shuffle_members only shuffles the values of col.
Adds pipeline classes for piping transformations: Pipeline, GeneratedPipeline, FixedGroupsPipeline.
Adds transformation classes: Transformation, GeneratedTransformation, FixedGroupsTransformation. Used by their respective pipeline class.
Adds triple_extremes() for arranging values in triplets with (highest, most middle, lowest), (second highest, second most middle, second lowest), etc. (Rearranger)
Adds order_by_aggregates argument to pair_extremes(). When using recursive pairing, this allows ordering the first num_pairings-1 pair identifier columns by the aggregate values instead of the identifiers.
Prepares package’s tests for checkmate 2.1.0.
Adds shuffle_hierarchy() for shuffling a multi-column hierarchy of groups. (Rearranger)
Adds optional recursion to pair_extremes(). This adds the num_pairings and balance arguments. Now returns one additional sorting factor per num_pairing level.
Note: Multiple of the new functions also have *_vec() versions that take and return vectors. The same can usually be achieved with the regular versions, but these wrappers make it easier and less verbose.
Adds center_max() for centering the highest value with values decreasing around it. (Rearranger)
Adds center_min() for centering the lowest value with values increasing around it. (Rearranger)
Adds position_max() for positioning the highest value with values decreasing around it. (Rearranger)
Adds position_min() for positioning the lowest value with values increasing around it. (Rearranger)
Adds pair_extremes() for arranging values as highest, lowest, second highest, second lowest, etc. (Rearranger)
Adds rev_windows() for reversing order window-wise. (Rearranger)
Adds closest_to() and furthest_from() for arranging values by how far they are from an origin (e.g. a target value / index in 1d). (Rearranger)
Adds roll_elements() for rolling/shifting the position of the elements. (Rearranger)
Adds cluster_groups() for moving data points into clusters around their group centroid. (Mutator)
Adds expand_distances() and expand_distances_each() for expanding values around an origin in any number of dimensions. (Mutator)
Adds dim_values() for dimming values in one dimension by their distance to around an n-dimensional origin. (Mutator)
Adds rotate_2d() and rotate_3d() for rotating values around an origin. (Mutator)
Adds swirl_2d() and swirl_3d() for rotating values around an origin. (Mutator)
Adds shear_2d() and shear_3d() for shearing values around an origin. (Mutator)
Adds flip_values() for flipping values around a center value. (Mutator)
Adds roll_values() and wrap_to_range() for rolling/shifting values and wrapping to a range. (Mutator)
Adds transfer_centroids() for transferring centroids from one data.frame to another. (Mutator)
Adds apply_transformation_matrix() for performing matrix multiplication with a given transformation matrix and a set of data.frame columns. Allows moving the origin before and after the transformation.
Adds circularize() for creating x-coordinates to a set of y-coordinates so they form a circle. (Former)
Adds hexagonalize() for creating x-coordinates to a set of y-coordinates so they form a hexagon. (Former)
Adds square() for creating x-coordinates to a set of y-coordinates so they form a square. (Former)
Adds triangularize() for creating x-coordinates to a set of y-coordinates so they form a triangle. (Former)
generate_clusters() for generating n-dimensional clusters. (Generator)Adds distance() for calculating distances to a specified origin. (Measuring function)
Adds angle() for calculating the angle between points and an origin. (Measuring function)
Adds vector_length() for calculating vector length/magnitude row-wise or column-wise. (Measuring function)
Adds min_max_scale() for scaling values to a specified range. (Scaler)
Adds to_unit_length() for scaling vectors to unit length row-wise or column-wise. (Scaler)
radians_to_degrees() and degrees_to_radians(). (Converters)Adds most_centered() for finding the coordinates of the data point closest to the centroid. (Helper)
Adds centroid() for finding the centroid from multiple vectors/columns (dimensions). (Helper)
Adds midrange() for finding the midrange of vectors/columns. (Helper)
Adds create_origin_fn() for creating a function for finding origin coordinates (like centroid()). (Helper)
Adds create_n_fn() for creating a function for finding the number of positions to move, e.g. in roll_elements(). (Helper)
Adds median_index() for finding the median index of each supplied vector. (Helper)
Adds quantile_index() for finding the nth quantile of the index of each supplied vector. (Helper)
