ggscatterhist | R Documentation |
Create a scatter plot with marginal histograms, density plots or box plots.
ggscatterhist( data, x, y, group = NULL, color = "black", fill = NA, palette = NULL, shape = 19, size = 2, linetype = "solid", bins = 30, margin.plot = c("density", "histogram", "boxplot"), margin.params = list(), margin.ggtheme = theme_void(), margin.space = FALSE, main.plot.size = 2, margin.plot.size = 1, title = NULL, xlab = NULL, ylab = NULL, legend = "top", ggtheme = theme_pubr(), print = TRUE, ... ) ## S3 method for class 'ggscatterhist' print( x, margin.space = FALSE, main.plot.size = 2, margin.plot.size = 1, title = NULL, legend = "top", ... )
data |
a data frame |
x |
an object of class |
y |
y variables for drawing. |
group |
a grouping variable. Change points color and shape by groups if
the options |
color, fill |
point colors. |
palette |
the color palette to be used for coloring or filling by groups. Allowed values include "grey" for grey color palettes; brewer palettes e.g. "RdBu", "Blues", ...; or custom color palette e.g. c("blue", "red"); and scientific journal palettes from ggsci R package, e.g.: "npg", "aaas", "lancet", "jco", "ucscgb", "uchicago", "simpsons" and "rickandmorty". |
shape |
point shape. See |
size |
Numeric value (e.g.: size = 1). change the size of points and outlines. |
linetype |
line type ("solid", "dashed", ...) |
bins |
Number of histogram bins. Defaults to 30. Pick a better value that fit to your data. |
margin.plot |
the type of the marginal plot. Default is "hist". |
margin.params |
parameters to be applied to the marginal plots. |
margin.ggtheme |
the theme of the marginal plot. Default is
|
margin.space |
logical value. If TRUE, adds space between the main plot and the marginal plot. |
main.plot.size |
the width of the main plot. Default is 2. |
margin.plot.size |
the width of the marginal plot. Default is 1. |
title |
plot main title. |
xlab |
character vector specifying x axis labels. Use xlab = FALSE to hide xlab. |
ylab |
character vector specifying y axis labels. Use ylab = FALSE to hide ylab. |
legend |
specify the legend position. Allowed values include: "top", "bottom", "left", "right". |
ggtheme |
the theme to be used for the scatter plot. Default is
|
print |
logical value. If |
... |
other arguments passed to the function |
an object of class ggscatterhist
, which is list of ggplots,
including the following elements:
sp: main scatter plot;
xplot: marginal x-axis plot;
yplot: marginal y-axis plot.
.
User can modify each of plot before printing.
