ggdag 0.2.13.9000

Introduced new functions query_conditional_independence(), test_conditional_independence(), and ggdag_conditional_independence() for detecting, testing, and visualizing implied conditional independencies in a given DAG and dataset (#139)
Introduced new functions aes_dag() and geom_dag() to simplify specification of ggplot code for most DAGs. Also refactored most quick plots to use these functions (#121)
Added new function geom_label_repel2() for more opinionated repelled labels that often look better on DAGs (#132)

Internal update to address upcoming changes in ggplot2 (#125, thanks @teunbrand)
Implemented automatic time-ordered coordinates for time_ordered_coords() and layout (#115)
Added geom_dag_label() to complement geom_dag_text() and the repel functions (#116)
Added pull_dag() and pull_dag_data() to extract DAG components, update_dag() and update_dag_data() to update DAG components, and as_tidy_dagitty() to construct DAGs from data frames (#117). Thanks to @lorenzoFabbri for inspiring some of the data-to-dag code in #90.

Fixed bug where ggdag was using wrong left_join() interface with dplyr 1.1.0 (#110)

Added new function time_ordered_coords() for calculating time-ordered coordinates (#88)
Addressed changes requested by CRAN, other changes in tidyverse (#87, #86, #85)

Fixed various bugs in calculating and visualizing paths (#75)
Fixed breaking changes from the upcoming release of ggplot2 3.4.0 (#79)
size is now deprecated for geom_dag_collider_edges() in favor of linewidth, related to #79.

Fixed issue with dag_adjustment_sets() when width option was low by extracting adjustment sets directly (#70)
Fixed issue with tidy_dagitty() that missed nodes with no edges attached. May cause minor breaking changes in randomized layouts. (#68)
Added the limit argument to dag_paths, ggdag_paths, and ggdag_paths_fan (see dagitty::paths) (#65).

tidy_dagitty() no longer allows the dendogram layout type (#62)
scale_adjusted() now correctly aligns legend types (#61)
ggdag no longer loads ggplot2 via Depends, instead importing it internally (#57).

Update vdiffr to be explicitly conditional (#51)
Fixed bug in activate_collider_paths() that causes an error where a collider had a high number of ancestors (#49)
Fixed bug in node_equivalent_dags() where extra columns did not get joined to new tidy DAG (#40)

Added vdiffr tests, as well as a basic test file for every .R file. (#27)
Updated roxygen2 version (#29)
Fixed bugs in dag_paths() and geom_dag_edges_fan() (#31)
Removed use of use_defaults() ggproto method in GeomDAGEdge (#33)
Use ggplot2::expansion() instead of expand_scale() when ggplot2 version is at least 3.3.0 and removed local version of expand_scale() (#34)

Fixed bug in ggdag_collider() where the aesthetics were flipped for the colors but not the labels (issue #15, b72e34b)
Used as.character.default() directly for working with characters to avoid dispatch error when the formula.tools package is attached (issue #17, 0f32bb4)

Fixed compatibility issue with ggraph 2.0.0 by changing to strength parameter in curved geoms
Fixed join bug in node_equivalent_class() that didn't account for the way dagitty returns DAGs with no direction
Fixed join bug in node_equivalent_class() that didn't check to node
Implemented is_false() to avoid dependency on R 3.5.0
improved edge lengths
add {} to adjustment set names to reflect convention
Set nodes to be unstyled by default
Changed default themes and scales to be more like base ggplot2
Added a NEWS.md file to track changes to the package.
