TDAstats 0.4.1

Bug Fixes

fixed potential error with updates in r-devel (matrix inherits from array)

Changes

calculate_homology now accepts any variable storing a distance matrix as long as it can be coerced to a matrix

Additions

added option for calculate_homology to return a data frame instead of a matrix
more code coverage
added support for flat persistence diagrams (flat = TRUE in plot_persist)

TDAstats 0.4.0

Bug Fixes

previous vignettes did not have citations and references section working properly; this has been fixed

Changes

added standardize parameter to calculate_homology and functionality to standardize point cloud size
added limit.num parameter to phom.dist and functionality to consider only "significant" topological features

Additions

code coverage has been increased
added support for distance matrix format for calculate_homology
vignette has been added showing use of new distance matrix format
phom.dist function to compare persistent homology of two point clouds/matrices

TDAstats 0.3.0

Bug fixes

fixed bug in plot_persist where setting a shorter axis limit would cause the reference diagonal to disappear (thank you, @corybrunson)

Changes

changing size of plot_persist output figures still preserves one-to-one length ratio of horizontal and vertical axes (fixed coordinate system; thank you, @corybrunson)

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

TDAstats 0.1.0

This is the first release of TDAstats.
