tdarec 0.2.0

column modification - BREAKING CHANGE

Per issue #19, the persistent homology computation steps now modify data set list-columns in place, and these and the disaggregation steps assign roles as conventional {recipes} steps. Previously, users could ignore the presence of persistence diagram list-columns because they were assigned the new role "persistent homology". They must now be manually removed or their roles updated. Alternatively, and preferably, the data set list-columns can have their roles updated to something other than "predictor", as illustrated in the README. Users now also lose access to the data set list-column unless they explicitly duplicate it before computing persistent homology.

unit tests

The minor version incorporates a patch to debug the vectorization tests, which had failed to run due to a prefix in the names of the generated test files. Once corrected, the tent template functions step failed one test due to missing parameters; this has been corrected.

default scale sequences

Default scale sequences derived from persistence diagrams now use extrema calculated after infinite values are dropped. This accommodates an upgrade to {ripserr} that returns features with deaths at infinity.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
