JOSS accepted version

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

Update submission to CRAN.

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.

Initial submission to JOSS

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

Initial release for CRAN

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.
