NEWS file for the ergm package

Changes in version 0.3.0

NEW FEATURES

• b1dsp(), b2dsp(), gwb1dsp(), and gwb2dsp() terms have been added, paralleling their ergm counterparts.

BUG FIXES

• Multilayer and multinetwork terms and functions such as gofN(), will now produce a sensible message if passed networks without multilayer and/or multinetwork metadata they require. Thanks to GitHub user @liluqi1991 for flagging this issue.

• gwespL(), espL(), and other terms from that family now correctly recycle their Ls.twopath= argument: if only one layer specification is given, it is used for both legs of the two-path.

• Layer logic implementation was reversing the arguments of noncommutative operators and functions.

OTHER USER-VISIBLE CHANGES

• Layer() now consistently uses the network and vertex attributes from the first observed layer for everything, and ignores and/or overwrites those of the other layers.

• When nesting network-combiners such as Networks() and Layer(), it is now an error to attempt to reference them out of order. That is, Networks(Layer(...))~L(~N(...)) is no longer allowed, since the multilayer specification is performed within the multinetwork.

• Layer() and Networks() documentation now informs the user that the resulting data structure's vertex and network attributes should be treated as read-only. This may change in the future.

• Support for networkLite and other alternative implementations of network's API has been added.

• gwespL(), gwdspL(), gwnspL(), when fixed=FALSE and other functions using a cutoff now terminate with an error if they encounter a network that exceeds it.

• *degreeL() family of terms has been removed. It never worked correctly and does not have a clear use case.

• blockdiag and blockdiagTNT proposals have been removed, as their performance is no better than the DyadGen-based dyadic constraint proposals.

• twostarL() no longer require the type= argument if called on an undirected network.

C-LEVEL FACILITIES

• A number of improvements and optimizations to the multilayer API.

• The exported Layer Logic API has been documented.

Changes in version 0.2.1

NEW FEATURES

• marg_cond_sim() now has an argument for how to handle when the constrained sample has a higher variance than the unconstrained. (Previously, it would always throw an error.)

BUG FIXES

• Fixes for documentation issues flagged by CRAN and compatibility with the latest roxygen2.

OTHER USER-VISIBLE CHANGES

• Some citations updated.

• When the optimized block-diagonal proposals encounter an initial network with off-block-diagonal edges, they no longer throw an error but rather use the ergm 4.6.0+ proposal declination API.

Changes in version 0.2.0

NEW FEATURES

• gofN objects now how augment and autoplot methods for Tidyverse and ggplot2 diagnostics.

• plot.gofN() and autoplot.gofN() are now more flexible in how they label extreme points via the id.label= argument.

BUG FIXES

• Fixed how parallel processing settings are handled in gofN() and marg_cond_sim().

Changes in version 0.1.2

BUG FIXES

• marg_cond_sim() now expects control.gofN() as its control= list.

• Some unit test tolerances have been loosed, making false positives less likely.

• Miscellaneous documentation fixes.

OTHER USER-VISIBLE CHANGES

• Tweaks to the combine_networks() API to make it more robust, space-efficient, and flexible; in particular to make it possible for tergm to depend on it rather than maintaining its own copy.

Changes in version 0.1.1

NEW FEATURES

• In the Layer(nw, attrlist) specification, attrlist= can now be a named vector, in which case the layers are renamed accordingly.

BUG FIXES

• Tolerance for some tests of the N() operator has been increased. This fixes a sporadic issue on M-series MacOS systems due to using a different linear algebra library.

• A bug in gofN() for valued ERGMs has been fixed.

OTHER USER-VISIBLE CHANGES

• A number of optimisations in multilayer ERGM code.

• [Layer] Logic backend now uses integer arithmetic, for a significant speed improvement, at the cost of behaviour slightly inconsistent with R's, such as / behaving as %/% (integer division).

Changes in version 0.1.0

NEW FEATURES

• Initial public release.
