rearrr 0.3.5

• Replaces use of dplyr::all_equal() with all.equal().

• Fixes test of quantile_index().

rearrr 0.3.4

• Updated documentation per CRAN requirements.

rearrr 0.3.3

• Makes tests compatible with purrr v1.0.1. (#2)

rearrr 0.3.2

• Makes use of suggested packages conditional on their presence.

• Makes testing conditional on the availability of xpectr.

• Makes tests compatible with the upcoming release of purrr v1. (#1)

• Fixes tidyselect-related warnings.

rearrr 0.3.1

• Regenerates documentation to fix html5 problem.

• Imports R6 to resolve note in R CMD check.

rearrr 0.3.0

• Breaking: Fixes bug in pair_extremes() 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 triplet_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.

rearrr 0.2.0

• 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.

rearrr 0.1.0

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.

New rearrangers

• 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)

New mutators

• 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.

Formers

• 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)

New generators

• Adds generate_clusters() for generating n-dimensional clusters. (Generator)

New measuring functions

• 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)

New scalers

• 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)

New converters

• Adds radians_to_degrees() and degrees_to_radians(). (Converters)

New helpers

• 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)
