archeofrag 0.9.1

Released: 2024-01-XX

Fourth major release.

  • Fix in the frag.layers.admixture() and frag.layers.cohesion() functions to handle pair of layers with only one layer having data.
  • In the frag.layers.cohesion() and frag.layers.admixture() functions, new optionnal parameters ("morphometry", "x", "y", "z") to pass to the frag.edges.weighting() function when applied to multiple pairs of layers.
  • New frag.graph.reduction() function to reduce the number of fragments of a fragmentation graph.
  • TODO : add a function to handle similarity relationships, generate
  • TODO : integrate the R Shiny application.

archeofrag 0.8.3

Released: 2022-11-16

  • add an option to remove the vertices in the frag.observer.failure() function.

archeofrag 0.8.2

Released: 2022-07-27

  • adding unit tests with testthat and test coverage analysis with covr.
  • fix the frag.simul.process() function.

archeofrag 0.8.1

Released: 2022-07-13

  • all functions from other packages are tagged with their package.
  • the RBGL is moved to the 'suggested' packages list, the functionalities related to planarity are now optional.
  • igraph functions' names are updated.
  • creation of a utils.R file, including internal functions to check the fragmentation graph and the "layer" argument.

archeofrag 0.8.0

Released: 2022-03-08

Third major release.

  • add license.
  • complete update of the vignette.

archeofrag 0.7.1

Released: 2022-02-17

  • when using frag.weight.edges() with xyz coordinates, the function now returns a graph with an edge attribute with the spatial distance between fragments
  • frag.layers.summarise() has three new parameters with default values to define the names of the colums with the cohesion and admixture values
  • the balance, disturbance, and aggreg.factor values returned by frag.get.parameters() are now rounded with two digits.
  • an error has been corrected in the asymetric.transport.from parameter of the frag.simul.process() function.

archeofrag 0.7.0

Released: 2021-04-26

Second major release, after complete revision of the documentation.

archeofrag 0.6.7

Released: 2021-04-12

  • new function frag.layers.compare() to generate simulated graphs for two deposition hypotheses, from the parameters of an observed graph.
  • new function frag.layers.summarise() for post-processing the results of the frag.layers.compare() function.
  • the frag.weight.edges() function now enables to weight the edges with morphometric and spatial distance values.

archeofrag 0.6.6

Released: 2021-03-30

  • the frag.simul.process() function has a new asymetric.transport.from parameter.
  • new features in frag.graph.plot(): if the graph has two layers, the fragments are distributed by layers in two different regions of the plot.
  • new make_sr_graph() function, to generate a connection graph from a frag.object.
  • frag.get.admixture() can now be applied to a graph with more than 2 layers.
  • frag.get.cohesion() can now be applied to a graph with more than 2 layers.
  • The edges of the graphs generated with frag.simul.process() are now internally weighted with the frag.edges.weighting() function.
  • frag.observer.failure(): new function to simulate the inaccuracy of an observer in determining the relationships between fragments.

archeofrag 0.6.0

Released: 2020-11-27

This is the first public release of the archeofrag package.
