dream 1.0.1 (2026-01-30)

Major Changes

• Implemented a new function to create time-dynamic risk sets for one- and two-mode relational event sequences. The new function is named create_riskset_dynamic().

Minor Changes

• Updated the remstats_-related C++ files to delete past network edges (i.e., past event weights) that are smaller than the past event cut off value (i.e., dyadic_weight) when this feature is selected by the user. That is, when the dyadic_weight argument is non-zero.

dream 1.0.0 (2026-01-19)

Major Changes

• Added a NEWS.md file to track changes to the package.
• Two key changes occured in the new version of dream package. First, the majority of functions now depend upon c++ routines via the Rccp package to improve computational runtime. For instance, the new function to compute the repetition network statistic, remstats_repetition(), is around 90 times faster than the previous function, computeRepetition(), in dream version 0.0.1. Secondly, the dream package has an updated API to allow better categorization for the functions. Please run ?dream for more details on the new API. Based upon this transition, the original functions are now deprecated starting on version 1.0.0, but remain available in this update.
• The following functions were deprecated for remstats_triads(): computeISP(), computeITP(), computeOSP(), computeTriads, and computeOTP().
• The following functions were deprecated for remstats_degree(): computeSenderOutdegree(), computeReceiverOutdegree(), computeSenderIndegree(), and computeReceiverIndegree().
• estimateREM() was deprecated for estimate_rem_logit().
• simulateREseq() was deprecated for simulate_rem_seq().
• computeFourCycles() was deprecated for remstats_fourcycles().
• computeRemDyadCut() was deprecated for remstats_dyadcut().
