spinifex v0.3.1

• Fixed ‘phi issue’ where manual tours were not consistent in their initial direction, now always move toward full contribution before 0 contribution.
• Interpolation of manual tours now handled in ggtour() synchronizes angle usage with {tourr} tours
• manual_tour() and related functions now handle 1D projections
• New functions: proto_highlight/1d() for highlighting specific points in ggtours
• New function: filmstrip(), creates a ggplot faceting the frames of a ggtour for a static output
• New dataset: penguins, from palmerpenguins::penguins, removed NA rows & reordered columns
• Added argument rownum_index to proto_text, for labeling subsets
• Experimental wrapper function spinifex::save_history, muting the noisy execution of tourr::save_history

spinifex v0.3.0!

• New ggproto api for visuals, see ?ggplot_tour() to get started!! – 10x new proto_* functions, essentially geoms_* for animated tours: basis/1d, point, origin/1d, density, text, hex, default/1d. – 2x animation funcs; animate_plotly() and aniamte_gganimate() – 2x internal utility functions
• New vignette demonstrating this api vignette("ggproto_api", "spinifex")
• Shiny app now imports .csv & .rds, code improved, uses new ggproto api – `run
• Fixed a format issue with the BeastCancer dataset

spinifex v0.2.8

• Vectorized all for loops
• manip_var_of(basis) suggests a variable to used based on the rank of the contributions of the basis.

Basis_* functions to find features of interest, powered by {Rdimtools}. - basis_olda() - basis_odp() - basis_onpp() - basis_olpp()

New util functions: - scale_sd() center and scale each variable by it’s standard deviation - scale_01() center and scale each variable to be between [0, 1] - basis_half_circle(), variable agnostic basis with minimal variable dependence. - as_history_array(), coerces an array of bases into the same attributes and class as returns of tourr::save_history()

spinifex v0.2.7

• Gives deprecated warning when using view_basis() and oblique_basis(), no longer listed in view_frame() documentation
• Fixed “radial_tour” shiny app to reflect argument changes
• Fixed example run time for render_plotly() going longer than 10 seconds

spinifex v0.2.6

• New argument, ggproto, accepts a list of {ggplot2} objects for more control over visual output
• New argument, aes_args, accepts a list of arguments to pass into the aes() call within geom_point(). This is used for variable mappings, such as color, but needs to be qualified as this is standard evaluation
• New argument, identity_args, accepts a list of arguments to pass call within geom_point(), but outside of aes(). This is used for scalar options or manually mapped vector such as point size or alpha
• New datasets, PimaIndiansDiabetes_long & PimaIndiansDiabetes_wide
• Fixed the centering of axes across frames
• Fixed scale_axes() to automatically scale to data rather than assume the data is scaled to [0, 1]
• Changed notation from “slide(s)” to “frame(s)” through-out
• Deprecated view_basis() and oblique_basis() in favor of view_frame()
• Fixed theta labeling on view_manip_space()
• Examples improved (simple case, adding more and more complexity) through-out
• Minor code, code comments, spelling, and grammar clean up through-out

spinifex v0.2.5

New utility

• theme_spinifex(), a ggplot theme, slightly lighter than theme_minimal().

Other changes

• Aesthetic arguments, which are now passed directly into geom_point(aes(...)) instead of hard-coded arguments
• Removed ‘col’ (color), ‘pch’ (point character), ‘cex’ (point size) and ‘alpha’ (transparency) from rendering functions. These options are now passed directly into the elipsis, ggplot2::geom_point(...)
• Added wrapper for gganimate::anim_save() in render_gganimate()
• Added wrapper for htmlwidgets::saveWidget() in render_plotly()
• Clarified and more consistent documentation

spinifex v0.2.0!

Demo shiny app

• run_app("radial_tour")

New functions

To accommodate interactive use, rather than predefined paths:

• oblique_basis()
• oblique_frame()
• run_app() New shiny app!

New utility functions

• map_absolute()
• is_orthonormal() slightly more general than tourr::is_orthonormal()

Other changes

• Added ‘cex’ (point size) and ‘alpha’ transparency arguments to rendering functions
• Argument naming and order consistency
• Clarified and more consistent documentation
• More defensive coding
