Radviz 2022-03-24

• changed some defaults in the plotting function to enable interactive visualitations through plotly
• added a scaling factor to the do.radviz function to counteract the compressing effect of a large number of springs
• plotting functions now use plot.radviz internally to avoid code duplication
• cleaned up links in the documentation

Radviz 2020-11-13

• reinstated the label options in text.radviz
• implemented anchor filtering for freeviz as a separate function

Radviz 2020-06-24

• fixed hexbin import for hexplot in the hexplot function
• fixed Rcpp import in do.optimFreeviz and do.optimGraphviz
• springs()` now returns the spring matrix rather than simply the channel names

Radviz 2020-03-27

• fixed hexbin import for hexplot
• rescalePlot will now issue a warning when some anchors cannot be interpreted after rescaling
• added a filtering option to plot.radviz to remove short anchors in Freeviz and Graphviz plots
• fixed some memory issues related to Freeviz & Graphviz C++ code

Radviz 2020-03-17

• subset now can be used directly on column names from the Radviz object
• optimization of anchor position using the Freeviz method from Demsar et al has been implemented by Nicolas Sauwen
• extended the optimization of anchor position from classes (Freeviz) to graphs (Graphviz)

Radviz 2020-02-03

• Fixed a bug related to arguments in smoothRadviz
• Fixed a bug in do.L where NA is returned if the column contains a single value after transformation
• Fixed a bug in do.radviz where creating Radviz objects from tbl_df could throw an error

Radviz 2020-01-10

After some testing the following enhancements have been made to the code:

• created a theme_radviz function, mostly to enable changing the overall font size
• label.size and label.color options have been reinstated, enabling each plot function to change the spring aspects
• added a springs function to access the channels used for projection
• fixed a bug where do.radviz would fail on a tbl_df or tibble object when some points could not be projected

Radviz now uses ggplot2 for plotting, enabling richer options for labeling and statistics.
