Create a scatter plot with density

Description

Create a scatter plot with density

Usage

JASPScatterPlot(
  x,
  y,
  group = NULL,
  xName = NULL,
  yName = NULL,
  addSmooth = TRUE,
  addSmoothCI = TRUE,
  smoothCIValue = 0.95,
  forceLinearSmooth = FALSE,
  plotAbove = c("density", "histogram", "none"),
  plotRight = c("density", "histogram", "none"),
  colorAreaUnderDensity = TRUE,
  alphaAreaUnderDensity = 0.5,
  showLegend = !is.null(group),
  legendTitle = NULL,
  emulateGgMarginal = FALSE,
  ...
)

Arguments

x	x variable.
y	y variable.
group	optional grouping variable.
xName	name on x-axis.
yName	name on y-axis.
addSmooth	should a smoothed regression line be drawn?
addSmoothCI	should a confidence interval be added to the smoothed regression line?
smoothCIValue	a numeric in (0, 1) indicating the confidence interval.
forceLinearSmooth	should the regression line be linear?
plotAbove	type of plot above the scatter plot.
plotRight	type of plot right of the scatter plot.
colorAreaUnderDensity	Logical, should the area under the density be colored?
alphaAreaUnderDensity	Real in [0, 1], transparency for area under density.
showLegend	Should the legend be shown?
legendTitle	A string for the title of the legend. NULL implies the legend is not shown.
emulateGgMarginal	Should the result be as similar as possible to ggMarginal? Overwrites other parameters.
...	passed to themeJaspRaw.

Details

The only change added when emulateGgMarginal = TRUE is that ggplot2::theme(plot.margin = unit(c(0, 0, 0.25, 0.25), "cm")) is added to the main plot

Examples

## Not run:

y <- rgamma(100, 1, 1)

                plotRight = "none")

# we can do the same with a grouping variable

                plotRight = "histogram")

# the color scheme can be changed with the global options:

graphOptions(palette = "viridis")

graphOptions(palette = "gray")
JASPScatterPlot(x = mtcars$mpg, y = mtcars$disp, group = mtcars$cyl)
graphOptions(palette = oldColor)

## NOT RUN
# spot the differences (if you find any report them to the package maintainer!)
plot <- JASPScatterPlot(x, y, xName = "Normal", yName = "Gamma", addSmooth = FALSE,
                        emulateGgMarginal = TRUE)
