Updated examine.outliers() and examine.changepoints() to plot more informative plots (with {ggplot2})
- These functions no longer print to the console
Added vignette teaching2.Rmd that also indicates these extensions
Added vignette teaching1.Rmd with the “How to start”

goldfish 1.5.0

New features

New DyNAM-i model available to model face-to-face interaction data, collected through video or RFID badges.

Functions to transform interaction data into DyNAM-compatible objects

defineGroups_interaction(interactions_data, actors, seed.randomization)

Estimation functions for the joining and leaving rates of a DyNAM-i model

estimate(
  dependent.events_interactions ~  1 + intercept(network_interactions, joining = 1) +
                                ego(actors$age,joining = 1, subType = "centered") +
                               ego(actors$age,joining = -1, subType = "centered"),
  model = "DyNAMi", subModel = "rate")

Estimation functions for the choice part of a DyNAM-i model

estimate(
  dependent.events_interactions ~ diff(actors$age,subType="averaged_sum") ,
  model = "DyNAMi", subModel = "choice", 
  estimationInit = list(opportunitiesList = opportunities))

New closure effects for model = "DyNAM" with subModel = "choice" and model = "REM". Documentation is updated accordingly.

cycle(bilatnet)
clSender(bilatnet)
clReceiver(bilatnet)
mixedCycle(list(bilatnet, contignet))
mixedClSender(list(bilatnet, contignet))
mixedClReceiver(list(bilatnet, contignet))

Minor improvements and fixes

Minor bugs in parsing and printing solved.
Solves some warnings regarding S3 generic/method consistency.
Solves no visible binding for global variables.
Documentation improvements creating new documentation pages aggregating similar functions on print-method and update-method.

Breaking changes

tertius_diff() and node_trans() are changed to tertiusDiff() and nodeTrans() complaining with naming convention.

goldfish 1.4.3

New features

mixedTrans() effect is created. It requires the definition of two networks to compute the number of two paths between nodes.
```
mixedTrans(list(bilatnet, contignet))
```

Minor improvements and fixes

estimate() no longer give warnings in R 4.0.0.
Classes and types checkings are revisited and extended.
linkEvents() is refactored as a S3 method.
New print or summary methods for goldfish objects are developed.
head() and tail() methods for nodes.goldfish, network.goldfish and dependent.goldfish are available.

goldfish 1.3.2

New features

tertius() and tertius_diff() effects are created. It requires the definition of a network and an attribute.
```
tertius_diff(bilatnet, states$gdp)
tertius(bilatnet, states$gdp)
```

goldfish 1.3.1

New features

estimate() now estimation routine in C for model = "DyNAM" and subModel = "choice_coordination".

goldfish 1.3.0

New features

estimate() parameter engine through estimationInit argument control the estimation routine used.

mod01 <- estimate(callsDependent ~ inertia + recip + trans,
                  model = "DyNAM", subModel = "choice",
                  estimationInit = list(engine = "gather_compute"))

estimate() now estimation routine in C except for model = "DyNAM" and subModel = "choice_coordination".
New effects definition for model = "DyNAM" and subModel = "rate".

Minor improvements and fixes

inertia fixed bug when weighted = TRUE.

Breaking changes
