Stats

28 stats

All stats

• identity no after_stat columns · 28 geoms · default for 28 Pass rows through unchanged. Default for most geoms: each mapped row becomes one mark with no aggregation.
• unique no after_stat columns · 11 geoms Keep one row per distinct mapped (x, y) pair (and group). Use when duplicate coordinates would overplot; default for none.
• manual no after_stat columns · 3 geoms Author-supplied after_stat values via params — skip automatic transforms when you already computed summaries.
• connect no after_stat columns · 2 geoms Expand successive points into connection vertices (linear, hv, vh, mid) for stepped or path-style joins between observations.
• count after_stat: count · 1 geom · default for 1 Count rows (or sum weights) per distinct x within each group. Default for geom_bar; publishes after_stat count.
• bin after_stat: count, density, ncount, ndensity · 4 geoms · default for 2 Bin continuous x into histogram breaks. Publishes count, density, ncount, and ndensity; default for histogram and freqpoly.
• bin_hex after_stat: count, density, ncount, ndensity · 1 geom · default for 1 Hexagonal 2D binning over continuous x and y. Publishes count/density columns for geom_hex heatmaps.
• bin_2d after_stat: count, density, ncount, ndensity · 1 geom · default for 1 Rectangular 2D binning over continuous x and y. Publishes count/density and bin edges for geom_bin_2d tiles.
• smooth after_stat: y, ymin, ymax, se · 1 geom · default for 1 Fit a smoother (lm or loess) and evaluate along x. Publishes y, ymin, ymax, and se; default for geom_smooth.
• quantile after_stat: y · 1 geom · default for 1 Estimate conditional quantiles of y given x. Publishes y at each requested probability; default for geom_quantile.
• boxplot after_stat: ymin, lower, middle, upper, ymax · 1 geom · default for 1 Five-number summary per group (hinges and whiskers). Publishes ymin, lower, middle, upper, ymax; default for geom_boxplot.
• density after_stat: density, count, scaled, ndensity · 1 geom · default for 1 1D Gaussian kernel density estimate along x. Publishes density, count, scaled, and ndensity; default for geom_density.
• summary after_stat: y, ymin, ymax · 4 geoms Collapse each discrete-x group to one summary (default mean ± se). Publishes y, ymin, ymax for error-style geoms.
• sum after_stat: n, prop · 2 geoms · default for 1 Count overlapping points at each (x, y) cell for geom_count. Publishes n and prop (not y).
• ydensity after_stat: density, count, scaled, violinwidth, y · 1 geom · default for 1 Kernel density along y for violin shapes. Publishes density, count, scaled, violinwidth, and y; default for geom_violin.
• function after_stat: y · 1 geom · default for 1 Evaluate a pure function on an x grid. Publishes y; default for geom_function when no data rows drive the mark.
• ecdf after_stat: ecdf · 1 geom Empirical cumulative distribution F̂(x). Publishes ecdf; pair with step or path geoms for CDF plots.
• summary_bin after_stat: y, ymin, ymax · 3 geoms Bin continuous x, then summarize y in each bin (mean ± se by default). Publishes y, ymin, ymax for binned summaries.
• contour after_stat: level · 1 geom · default for 1 Marching-squares isolines over a regular x×y×z grid. Publishes level; default for geom_contour.
• align no after_stat columns · 2 geoms Interpolate series onto a shared x grid so continuous-x stacks and overlays line up (stack-friendly zeros outside range).
• density_2d after_stat: level, density · 1 geom · default for 1 Bivariate KDE with isolines. Publishes level and density; default for geom_density_2d.
• density_2d_filled after_stat: level, density · 1 geom · default for 1 Bivariate KDE with closed density rings for filled contours. Publishes level and density; default for geom_density_2d_filled.
• bindot after_stat: stackpos · 1 geom · default for 1 Histodot binning for geom_dotplot: one stack position per observation. Publishes stackpos (and bin occupancy).
• ellipse no after_stat columns · 1 geom Confidence ellipse over bivariate points (level and type from params). Passes geometry suited to path/polygon-style marks.
• sf no after_stat columns · 1 geom · default for 1 Simple-features geometry expansion for geom_sf: multiparts and holes become drawable rings without after_stat columns.
• sf_coordinates no after_stat columns · 2 geoms · default for 2 Label anchors from SF geometries for geom_sf_text and geom_sf_label (one point per feature or part).
• qq after_stat: sample, theoretical · 1 geom · default for 1 Sample vs theoretical quantiles for Q–Q plots. Publishes sample and theoretical; default for geom_qq.
• qq_line after_stat: sample, theoretical · 1 geom · default for 1 Reference line through Q–Q sample/theoretical quantiles. Publishes sample and theoretical; default for geom_qq_line.

How to set a stat

On any geom shell, pass the stat prop. Only values listed on that geom's Geoms page validate. Omit it to use the geom default.
