Version 0.6.5

  • Now Depends R (>= 4.1.0) to handle |>
  • Added lda() objects to those handled by reflect()
  • Illustrate reflection in ggbiplot examples

Version 0.6.4

  • Documented solution to 'scale_color_discrete() produces two legends' #2
  • Fix glitch with axis labels
  • ggbiplot gains geom.ind and geom.var arguments for more flexlible handling of the geometries used to display the observation points and variable labels.

Version 0.6.3

  • Fix axis label spacing
  • ggbiplot gains a clip argument to control if points, labels, etc. are clipped to the axis limits.

Version 0.6.2

This is a modest upgrade to the initial release, adding a number of features.

  • corrected small bugs in ggbiplot() and ggscreeplot()`
  • reflect() now also reflects supplementary variables from FactoMineR::PCA()
  • added support for ade4::dudi.pca()
  • ggbiplot() gains an axis.title argument
  • ggscreeplot() gains color, shape, linetype and linewidth arguments
  • Added get_SVD() intended the simplify the interface to various PCA functions.
  • Now use get_SVD() in ggbiplot() and ggscreeplot()
  • Extend some examples, requiring Depends:ggplot2

Version 0.6.1

  • Revised documentation for ggscreeplot()
  • data(crime) used in README giving a more complete example.
  • Fixed links reported as 301s
  • Published pkgdown site

Version 0.6.0

  • Use geom_polygon() rather than geom_path() for ellipses to allow them to be filled.
  • Added var.factor argument to expand or reflect the variable vectors
  • Moved points/labels code earlier so ellipses and variable vectors are not obscured
  • Replaced internal calculation of ellipses with stat_ellipse()
  • Now allow ellipses to be filled (geom_polygon()) or unfilled (geom_path())
  • Added hex logo
  • Added iris example to README
  • Removed Imports: dplyr, purrr as no longer needed

Version 0.56

  • Fixed many documentation errors and warnings
  • Use roxygen2 for documentation
  • added varname.color to replace fixed muted("red")
  • tweaked arrow style
  • increased default thickness of variable vectors
  • add point.size argument
