CohortMethod 3.1.0


  1. Added plotTimeToEvent function

  2. Deprecating addExposureDaysToStart and addExposureDaysToEnd arguments, adding new arguments called startAnchor and endAnchor. The hope is this is less confusing.

  3. Fixing random seeds for reproducibility.


  1. No longer overriding ffmaxbytes and ffbatchbytes in .onLoad. Instead relying on FeatureExtraction to do that. Part of fixing chunk.default error caused by ff package on R v3.6.0 on machines with lots of memory.

  2. Correct calculation in original population count when using study end date.

CohortMethod 3.0.2


  1. (Much) faster variable ratio matching
