[R] [R-pkgs] PST version 0.81

[Alexis Gabadinho]

Dear R users,

The PST package (version 0.81) is now available on the CRAN. It enables 
the modelling and analysis of categorical sequences with probabilistic 
suffix trees (PST).

The package fits variable length Markov chain models and store them in 
PSTs. It is specifically adapted to the field of social sciences by 
allowing to learn VLMC models from sets of individual sequences possibly 
containing missing values, and to account for case weights.

Fitted PSTs can be used among other for sequence prediction (pattern 
mining), imputation and artificial sequences generation. The package 
also includes original visualization tools of both the model and 
outcomes of sequence prediction.
