TraMineR and TraMineRextras updates

TraMineR 2.2

A new version of TraMineR has been released on the CRAN.

Main changes are:

  • Improvements of the seqdist function (computation of dissimilarities)
    • vector of state-dependent indels now supported by all distance methods that require an indel value.
    • indel has a new default value “auto” to automatically compute a suitable indel value from the provided sm (substitution costs) matrix or method.
    • refseq (reference sequence to compute dissimilarities from), including refseq stated as a sequence object, now supported by all distance methods.
    • normalization now applicable to all edit distances.
  • seqdef now also assigns a default color palette when the alphabet is of size greater than 12.
  • New rbind method for state sequence (stslist) objects that proves useful for merging two groups of sequence data, or simply to add a sequence to a sequence object.

For more details see the NEWS file and the online help documentation of the concerned functions.

TraMineRextras 0.6

A new version 0.6 of TraMineRextras has also been released on the CRAN.

Main changes are

  • a new function seqCompare that implements the Likelihood ratio test (LRT) and delta BIC introduced in the forthcoming paper of Tim F. Liao & Anette E. Fasang. “Comparing Groups of Life Course Sequences Using the Bayesian Information Criterion and the Likelihood Ratio Test.” Sociological Methodology xx:xxx–xxx.
  • seplot.rf gains a new argument which.plot.
  • seqgranularity has two new methods “first.valid” and “last.valid”  for sequences with missing values.

For more details see the NEWS file and the online help documentation of the concerned functions.
