TDAstats Versions Save

R pipeline for computing persistent homology in topological data analysis. See https://doi.org/10.21105/joss.00860 for more details.

v0.3.2

5 years ago
  • Figure size has been updated for JOSS paper
  • Code coverage has been added (codecov.io)
  • Minor changes (bug fixes, etc.)

v0.3.0

5 years ago

Version 0.3.0 primarily includes bug and stylistic imperfections from v0.2.0. Resubmitted to avoid being removed from CRAN due to index_t clash on Solaris systems.

v0.2.0

5 years ago

TDAstats 0.2.0

Bug fixes

  • fixed bug in permutation_test function that resulted in NAs in output
  • fixed naming clash with index_t in C++ code; should make TDAstats compatible with Solaris systems

Changes

  • added dim parameter to permutation_test function to allow users to select maximum dimension for homology comparison

Additions

  • added automated testing using testthat package
  • 4 sample datasets for users to learn/test TDAstats (and probably to follow future vignettes): unif2d, unif3d, circle2d, sphere3d
  • added 2 vignettes introducing features of TDAstats to user through text and a case study

v0.1.0

5 years ago

Includes basic functionality of: (1) calculation of persistent homology with Ripser; (2) visualization of persistent homology with persistence diagrams and topological barcodes using ggplot2; (3) non-parametric statistical inference of persistent homology using a permutation test.
