RandomWalker 0.3.0

CRAN release: 2025-05-06

Breaking Changes

  1. Fix #107 - This change allows for the generation of random walks with up to 3 dimensions. Due to this what was the x column is now called step_number for all random walk functions including rw30(). The x column is now the first dimension of a 2D/3D random walk.

New Features

  1. Fix #105 - Add internal function rand_walk_column_names() to generate column names for random walks.
  2. Fix #142 - Add vector function confidence_interval() to generate confidence interval tibble.
  3. Fix #71 - Add function subset_walks() to subset random walks by max or min value.

Minor Fixes and Improvements

  1. Fix #107 - Add .dimensions parameter to random walk functions to allow for the generation of random walks with up to 3 dimensions!
