Value

A plot containing jittered points, a boxplot and a density plot or histogram illustrating the distribution of every group of the data under evaluation.

Arguments

dat: A data frame.
yvar: The name of the field containing values to be plotted.
xvar: The name of the field containing the grouping variable (defaults to NULL).
ylim: Limits for the y-axis. Defaults to NULL. If provided, should be a 2-element vector containing the upper and lower limits.
xlb: Label for the x-axis.
ylb: Label for the y-axis.
identity_line: Show a line of identity? Default FALSE.
identity_value: If an identity line is shown, it will be drawn horizontally at this y-value (default 0).
he_adjust: If he_slab_type is "pdf", bandwidth for the density estimator is adjusted by multiplying it by this value.
he_width: Width of the halfeye component of the plot (default 0.6).
he_justification: Justification of the halfeye component of the plot (default -0.2).
he_col: Color for the halfeye component of the plot.
he_fill: Fill color for the halfeye component of the plot.
he_alpha: Alpha for the halfeye component of the plot (default 0.9).
he_slab_type: The type of slab function to calculate for the halfeye component of the plot: probability density (or mass) function ("pdf", the default), cumulative distribution function ("cdf"), complementary CDF ("ccdf") or histogram ("histogram").
he_breaks: If slab_type is "histogram", the breaks parameter that is passed to hist() to determine where to put breaks in the histogram.
he_outline_bars: If slab_type is "histogram", determines if outlines in between the bars are drawn when the slab_color aesthetic is used. If FALSE (the default), the outline is drawn only along the tops of the bars; if TRUE, outlines in between bars are also drawn.
he_point_interval: A function from the ggdist::point_interval family (e.g., median_qi, mean_qi, mode_hdi, etc), or a string giving the name of a function from that family (e.g., "median_qi", "mean_qi", "mode_hdi", etc. This function determines the point summary (typically mean, median, or mode) and interval type (quantile interval, qi; highest-density interval, hdi; or highest-density continuous interval, hdci). Output will be converted to the appropriate x- or y-based aesthetics depending on the value of orientation.
he_point_alpha: Alpha for the point.
he_point_fill: Fill colour for the point.
he_point_colour: Colour for the point.
he_point_size: Size for the point.
bxp_width: Width of the boxplot component (default 0.12).
bxp_outlier_col: Color for outliers in the boxplot component.
bxp_outlier_fill: Fill color for outliers in the boxplot component.
bxp_outlier_shape: Shape for outliers in the boxplot component.
bxp_outlier_size: Size for outliers in the boxplot component.
bxp_col: Color for the boxplot component.
bxp_fill: Fill color for the boxplot component.
bxp_alpha: Alpha for the boxplot component.
bxp_notch: If FALSE (default) make a standard box plot. If TRUE, make a notched box plot. Notches are used to compare groups; if the notches of two boxes do not overlap, this suggests that the medians are significantly different.
bxp_notchwidth: For a notched box plot, width of the notch relative to the body (default 0.5).
hp_alpha: Alpha for the jitter.
hp_col: Color for the jitter.
hp_size: Size for the jitter.
hp_shape: Shape for the jitter.
na.rm: If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.
