ggnetwork 0.5.8
===============

Many thanks to Uwe Ligges and [Julia Fukuyama](https://github.com/jfukuyama), from the [`phyloseqGraphTest` package](https://github.com/jfukuyama/phyloseqGraphTest), who helped with pushing the package forward while preserving its reverse dependencies.

## Minor improvements and fixes

* Fixed a bug that caused networks of class `igraph` to lose edge attributes.

ggnetwork 0.5.7
===============

## Minor improvements and fixes

* Adjustments to avoid any [issues with `class()`](https://developer.r-project.org/Blog/public/2019/11/09/when-you-think-class.-think-again/index.html).

* Fixed some faulty and/or unsecure URLs (thanks to Uwe Ligges).

ggnetwork 0.5.6
===============

Due to a bugfix in `statnet.common` 4.2.0, `ggnetwork` now requires R ≥ 3.5 (#45).

## Minor improvements and fixes

* Added a `scale` argument that makes it possible to pass meaningful spatial 
coordinates like latitude and longitude without (re)scaling (#48).

* Finished fixing a bug affecting 2-node, 1-tie networks of class `igraph` (#12). Thanks to [Mickaël Canouil](https://github.com/mcanouil) (#20) and [Zachary Charlop-Powers](https://github.com/zachcp) (#24).

* Added a `stringsAsFactors` argument that allows to import vertex and edge 
attributes as character strings instead of factors, which remains the default 
behaviour (#53).

* Fixed a bug that caused `igraph` vertex attributes to be returned in a 
different type than the original attribute (#54).

* Fixed a bug that made it impossible to convert edge attributes provided as
character strings into factors (#55), which is now the case by default (#53).


ggnetwork 0.5.5
===============

Many thanks to [Mickaël Canouil](https://github.com/mcanouil), who contributed all changes below (#42).

## Repository changes

* Add `README.Rmd` (replace `README.md`), 
  + use badges.
  + list all GitHub contributors.
  + add Contributing, Code of Conduct Issue Template and Support markdown file (`usethis`).

* Improve `.travis.yml`,
  + use `pkgdown` for website deployment.
      - add `_pkgdown.yml` configuration file.
  + use `covr` for code coverage.
      - add default `codecov.yml` configuration file.
  
* Add `ggnetwork.Rproj`, for ease of use within Rstudio.

## Minor improvements and fixes

* In `DESCRIPTION`,
  + update RoxygenNote version.
  + remove `ggplot2` from `Enhances` field.
  + add `Collate` field to load sequentially the functions.
  + move `igraph` to `Imports` field.
  
* Remove `inst/doc/` directory, *i.e.*, the vignette is part of the `pkgdown` website.

* Use tidy code style.

* In `R/fortify-igraph.R` and `R/fortify-network.R`, 
  + use subsetting functions instead of `with` and `transform` (*i.e.*, intended to be use interactively).
  + fix issue from CRAN check with undefined global variables.
  + remove namespace loading for `sna` package (*i.e.*, `gplot.layout.*` functions).
  
* In `R/geom-nodes.R` and `R/geom-edges.R`, 
  + remove unnecessary "@importFom".
  + add missing function packages prefix.
  
* In `R/ggnetwork.R`, `switch` and `tryCatch` to make the `igraph` and `network` testing consistent.
  
* In `R/utilities.R`, reexport `fortify` and `unit` from `ggplot2`.
