• Updated version to indicate some nice new additions for the package
  • Fix to duplicating bases during interpolate
  • New display type: animate_idx
  • Edges now working correctly in display_groupxy
  • Interpolate had an error in calculating distance between planes which is fixed
  • Small changes in prep for CRAN
  • Time for it to be a full version number
  • Changed line colours to take a factor, and be handled the same as points.
  • Fixed sizing issue in display_trails
  • Set rescale default to be FALSE
  • display_dist() has controls to change binwidth, and to scale the height of the bars or density in each projection.
  • Finally modified density plot to include colours
  • Added palette option display functions
  • Fixed a bug in display_slice(), display_density2d(), display_groupxy(), display_pca(), display_sage(), manual_slice(), caused by changes in handling colour vector in display_xy()
  • Added line with for edges to display_xy()
  • Changed default colour scale
  • Bug fixes
  • Support for displaying point labels
  • Color and shape legend added for animate_xy
  • Added a render_anim to create a plotly animation
  • Fixed a bug in save_history so that if start is provided it doesn’t get duplicated
  • Fix to is_orthonormal so it doesn’t just stop if not a matrix
  • Added routine to draw projected data and axes
  • Added argument to render tours as gifs without looping
  • Shorten run time of several examples
  • Changed most dontrun to donttest
  • Fix examples based on CRAN checks
  • splines2d force data to be data frame for model
  • splines2d function fixed to pass in the data as required by mgcv::gam
  • Handle problem of mismatching number of frames in render_gif
  • Slice center navigation now has positions
  • Fixed bug in slice tour when anchor was not provided
  • Added slice center guide
  • Adding manual slicing
  • Error fixed in is_orthonormalise(), which is to check whether a vector is normalised
  • Error fixed in orthonormalise_by(), which needed to run over columns of new matrix, too
  • A radial tour is added that will allow a variable to be zero’d from a projection.

  • Fixes made according to CRAN requests

  • Two vignettes have been added to help users get started.

  • Little tour now cycles twice through variable list, in a randomised order.

  • Two new projection pursuit indexes have been added, based on function from the archived package mbgraphic.

  • A slice tour is now available using the function animate_slice(). A new index for searching for interesting slices is available.

  • A principal component analysis tour display is now available, that renders the axes of the original variables. This requires appropriate scaling of data ahead of time. See the example code.

  • A new record option is available to print out diagnostic information for every step. Bind the animate code to a name will store the record object. The ferrn package at https://github.com/huizezhang-sherry/ferrn can be used to diagnose the optimisation techniques.

  • Improvements to the optimisation functions have been made: search_better has an interrupt if a higher index is achieved mid-path; search_polish takes a best basis from another routine, and makes small steps to get a very best projection close by.

  • Set the default fps to 10, to compatibly draw with RStudio window.

  • Added a NEWS.md file to track changes to the package.

  • Indexes holes and cmass functions now follow the same style as lda_pp and pda_pp, which means that you need to use them with holes(), and cmass()

  • A new display type, groupxy has been added, which will run the same tour on subsets of the data in a split plot window
