ggstats vs PurpleAir
A side-by-side editorial comparison of ggstats and PurpleAir — release velocity, themes, recent moves, and the top alternatives to consider.

ggstats vs PurpleAir: at a glance
What is ggstats?
ggstats keeps widening what a coefficient or Likert plot can be
ggstats extends ggplot2 with statistical plotting: model coefficient plots, Likert and diverging bar charts, proportion geometries and the helpers that make them behave. Recent releases have added an experimental gglikert_side(), left and right total columns for gglikert(), and survey-object support across the Likert family. Development is steady and CRAN-paced, with releases every two to three months.
What is PurpleAir?
The R client for PurpleAir sensors keeps finding its time-averaging was wrong.
PurpleAir is a small R client for the PurpleAir air quality sensor API, covering sensor queries, historical readings, and — more recently — finding a sensor on the local network by IP address and id. Authentication has been simplified to an environment variable only, with the redundant key argument removed. The package is maintained reactively, and most of what ships is correctness work on the queries it already makes.

ggstats keeps widening what a coefficient or Likert plot can be
◆ Current state
ggstats extends ggplot2 with statistical plotting: model coefficient plots, Likert and diverging bar charts, proportion geometries and the helpers that make them behave. Recent releases have added an experimental gglikert_side(), left and right total columns for gglikert(), and survey-object support across the Likert family. Development is steady and CRAN-paced, with releases every two to three months.
◆ Where it's heading
Two long-running threads. The coefficient side has been consolidating — ggcoef_multinom() and ggcoef_multicomponents() soft-deprecated in favour of a unified ggcoef_model() with group_by, plus new ggcoef_dodged() and ggcoef_faceted() variants. The Likert side keeps expanding outward instead, absorbing survey objects, total columns and side-by-side layouts. Underneath both is a steady tax of ggplot2 and vctrs compatibility work, including tracking the geom_errorbarh() deprecation in ggplot2 4.0.0.
◆ Prediction
Expect gglikert_side() to lose its experimental status once its interface settles, and the deprecated multinomial entry points to be removed in a future release now that ggcoef_model() covers their cases.
PurpleAir
0.0ANALYTICS
The R client for PurpleAir sensors keeps finding its time-averaging was wrong.
◆ Current state
PurpleAir is a small R client for the PurpleAir air quality sensor API, covering sensor queries, historical readings, and — more recently — finding a sensor on the local network by IP address and id. Authentication has been simplified to an environment variable only, with the redundant key argument removed. The package is maintained reactively, and most of what ships is correctness work on the queries it already makes.
◆ Where it's heading
The recurring theme is time aggregation. Weekly, monthly and yearly average intervals were wrong and fixed in one release; the weekly average was wrong again and fixed in the next. For an air quality package that is not incidental — averaging window is what turns a stream of sensor readings into an exposure estimate, and downstream analyses inherit the error silently. The other thread is failing earlier and more clearly: explicit errors for spatial inputs the sensor query does not accept, better index parsing so malformed requests never reach the API, and handling for history calls that return nothing. Local sensor discovery is the one genuine capability addition, opening a path that does not depend on the cloud API at all.
◆ Prediction
On this record, further aggregation and input-validation fixes are the likeliest next releases; whether local network access grows past discovery into full local data retrieval is not something the entries indicate.
