In tabula: Analysis and Visualization of Archaeological Count Data

tabula 3.0.0

Bugfixes & changes

• Add seriograph() to display a Ford diagram highlighting the relationships between rows and columns.

Bugfixes & changes

• EPPM argument of plot_ford() is defunct (use seriograph() instead).

Breaking changes

• Seriation methods are no longer reexported from kairos.

tabula 1.8.0

Seriation methods are now reexported from kairos and will be removed in a future release.

Internals

• Reduce required R version to 3.2.
• Error handling has been revised and error messages have been harmonized.
• Refer to ggplot2 functions using :: (stop importing the entire package).
• Use vdiffr to test graphical output.
• Replace FactoMinerR::CA() with ca::ca() (this avoids having to install all {FactoMineR} dependencies when only one function is used).
• Remove dplyr from the imported packages, move magrittr to suggested packages.

Experimental

• When a Matrix object is first created, an identifier (UUID v4) is generated with generate_uuid(). This ID is preserved when coercing to another class. This makes it possible to identify objects representing the same initial data and associate them with the results of specific computations.
• get_coordinates() and set_coordinates<- allow to extract and replace spatial informations in AbundanceMatrix objects.
• get_features() allows to convert an AbundanceMatrix object to a data.frame. It is intended for compatibility with the sf package.
