In ggfixest: Dedicated 'ggplot2' Methods for 'fixest' Objects

ggfixest 0.4.0

New features

• Users can now supply a list of vcov arguments to compare multiple SE adjustments on the fly. (#65)

r est = est = feols(flipper_len ~ bill_len | species, penguins) ggcoefplot(est, vcov = list("iid", "hc1", ~species))

Bug fixes

• The keep and drop arguments now work correctly with a list of models. Thanks to @femdias for the report. (#60)
• If a (named) list of models if provided to either ggcoefplot or ggiplot then the original order is preserved for grouping and facet behaviour (#63)

Internals

• Bump ggplot2 dependency to v4.0.0 and update test snapshots. (#55, #59)
• Bump fixest dependency to v0.13.0 and update tests. (#58, #59)

ggfixest 0.3.0

New features

• The new aggr_es(..., period = "diff") convenience keyword argument allows users to estimate the difference between the (mean) post- and pre-treatment periods. Thanks to @FBrunamonti for the suggestion. (#52).

Internals

• Bump svglite dependency version and update test snapshots. (#51)

ggfixest 0.2.0

Bug fixes

• Fix missing "hypothesis" attribute for aggr_es objects. (#43)
• Fix dodge misalignment between points and lines with multi fixest objects. (#44)

Internals

• Replace ggh4x dependency with legendry. (#41 @teunbrand)

Misc

• Minor website and documentation improvements.

ggfixest 0.1.0

First CRAN release!

New features

• The aggr_es function now supports numeric sequences for aggregating a specific subset of periods, in addition to the existing keyword strings like "pre" or "post". This functionality also passes through to the higher order plotting functions that call aggr_es under the hood. For example, ggiplot(est, aggr_eff = 6:8). (#33)
• Users can now adjust standard errors for model objects on-the-fly at plot time, by passing an appropriate argument, e.g. ggcoefplot(est, vcov = "hc1"). These on-the-fly adjustments are done via summary.fixest, and so the effect is just the same as passing an adjusted object directly, e.g. ggcoefplot(summary(est, vcov = "hc1")). However, it may prove more convenient for simultaneously adjusting a list of multiple models, e.g. ggcoefplot(list(est1, est2, est3), vcov = "hc1"). (#35)

ggfixest 0.0.3

Breaking change

• The package name has been changed to ggfixest (#29).

ggiplot 0.0.2

New features

• Support for ggcoefplot, a ggplot equivalent of coefplot (#28).
• Support pt.size argument for controlling the size of point markers (#27). Thanks @jcvdav.
• Support keep and drop arguments for subsetting coefficients (#22).

Bug fixes and breaking changes

• Fix naming mismatch in multiple estimation with different time periods (#10). Thanks @brockmwilson.
• Slight tweak to default theme, which now uses dotted grid lines to more closely match iplot() (#e5cf0b0).
• Correctly parse formula-transformed dependent variable names, e.g. log(y (#20).
• The confidence intervals for some figures may be slightly wider due to upstream changes in fixest (#25; see also https://github.com/lrberge/fixest/pull/408).

Internals

• Add a (visual) test suite (#12 with several increments thereafter). Thanks to @vincentarelbundock for ~~tinyviztest~~ tinysnapshot!
• Switch to marginaleffects::hypotheses() internally for aggr_es() to match the upstream changes in marginaleffects.
• Simplify multi_fixest object parsing (#19).
• Minor documentation improvements.

ggiplot 0.0.1

• Tweaks to plot output, including integer breaks on x-axis (where appropriate) and allow additional user-level control (e.g. CI alpha or width levels)
• Support multiple confidence levels (#2, #5)
• Support multiple LHS variables (#1)
• Added a NEWS.md file to track changes to the package.
