In tourr: Tour Methods for Multivariate Data Visualisation

tourr 1.1.0

• Updated version to indicate some nice new additions for the package

tourr 1.0.2

• Fix to duplicating bases during interpolate
• New display type: animate_idx

tourr 1.0.1

• Edges now working correctly in display_groupxy
• Interpolate had an error in calculating distance between planes which is fixed

tourr 1.0.0

• Small changes in prep for CRAN
• Time for it to be a full version number

tourr 0.6.18

• Changed line colours to take a factor, and be handled the same as points.

tourr 0.6.17

• Fixed sizing issue in display_trails

tourr 0.6.16

• Set rescale default to be FALSE

tourr 0.6.15

• display_dist() has controls to change binwidth, and to scale the height of the bars or density in each projection.

tourr 0.6.14

• Finally modified density plot to include colours

tourr 0.6.13

• Added palette option display functions

tourr 0.6.12

• 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()

tourr 0.6.11

• Added line with for edges to display_xy()

tourr 0.6.10

• Changed default colour scale

tourr 0.6.9

• Bug fixes

tourr 0.6.8

• Support for displaying point labels

tourr 0.6.7

• Color and shape legend added for animate_xy

tourr 0.6.6

• Added a render_anim to create a plotly animation

tourr 0.6.5

• 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

tourr 0.6.4

• Added routine to draw projected data and axes

tourr 0.6.3

• Added argument to render tours as gifs without looping

tourr 0.6.2

• 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

tourr 0.6.1

• A radial tour is added that will allow a variable to be zero'd from a projection.

• Fixes made according to CRAN requests

tourr 0.6.0

• 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.

tourr 0.5.6

• 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
