rEMM 1.2.3 (10/13/2026)

  • Added a getting started vignette.
  • Added a vignette on modeling temporal structure with stream clusterers and TRACDS.

Updates

  • Updated and added tests.
  • Switch to roxygen documentation.
  • Updated plotting and graph conversion to use current igraph function names.

Bugfixes

  • Fixed multi-step prediction, default fading, copied temporal model fading, and state bookkeeping when merging, removing, or updating states. TRAC now preserves cluster labels in its centers and temporal model.

Changes in version 1.2.2 (08/09/2025)

  • Fixed partial argument matching issues.

  • removed C++ code.
  • proxy and igraph are now imported.

Changes in version 1.2.0 (06/25/2022)

CRAN release: 2022-06-25

  • added interface for package stream

Changes in version 1.1.1 (05/31/2022)

CRAN release: 2022-05-31

Changes in version 1.0-11 (07/23/2015)

CRAN release: 2015-07-24

  • Fixed NAMESPACE (non-standard imports)

Changes in version 1.0-9 (5/15/2015)

CRAN release: 2015-05-15

  • Fixed dependencies in NAMESPACE
  • Fixed problems with testthat

Changes in version 1.0-8 (1/14/2014)

CRAN release: 2014-01-14

  • score: match_clusters can now be “exact”, “nn” or “weighted”, where weighted replaces all the weighted scores.
  • added smooth_transitions (experimental)
  • plus_one is now called prior (since it adds a uniform prior for transition probabilities)
  • score has now an argument called normalize

Changes in version 1.0-7

CRAN release: 2013-08-11

  • improved plot for tNN
  • tNN: centroids stop moving to prevent 2 clusters from colliding
  • fixed bug with getting transitions from a TRACDS object with 0 transitions
  • find_clusters also accepts now a threshold factor for match_clusters
  • score: weights for scoring are now normalized for threshold
  • transition from igraph0 to igraph

Changes in version 1.0-6

CRAN release: 2012-05-30

  • Improved performance for prune()
  • Added object.size() which also reports memory used by the model
  • Switched to igraph0

Changes in version 1.0-5

CRAN release: 2012-04-09

  • Added several methods for score.
  • Threshold for pruning and finding rare clusters/transitions is now less or equal instead of just less

Changes in version 1.0-3

CRAN release: 2012-02-08

  • Finished the transition to reference objects implemented using environments.
  • transition_table() now has for consistency also the default of add_one set to FALSE.
  • last_clustering() was added as an accessor function to tNN.
  • ‘igraph’ is now the default plot method.
  • Added combining EMMs.
  • Added reclustering using tNN.
  • Added coloring of states and transitions to plot().
  • Added coercion functions as.igraph() and as.graph from TRACDS.

Changes in version 1.0-2

CRAN release: 2011-07-26
