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
