ClassDiscovery 3.3.13 (2020-11-11)

BUG FIXES

• Not exactly sure if this qualifies as a bug fix: modified one of the man pages to remove an unnecessary cross-reference to a package that might not be available.

ClassDiscovery 3.3.10

BUG FIXES

• Not exactly sure if this qualifies as a bug fix: modified some of the test scripts so that they don't raise errors (because of not matching the output) on a few of the extra installations tested by CRAN. The underlying issue appears to be in the results of "hclust", which finds the same groups but assigns them different cluster-labels on some machines.

UPDATES

• Modified use of S4 classes to avoid deprecated and discouraged elements.
