We ll use the ggpubr package to create the plots and the cowplot package to align the graphs.
In the r code above we used the argument stat identity to make barplots.
Prerequisites data preparation create histogram with density distribution on the same y axis using a.
Description usage arguments details aesthetics examples.
In this article you will learn how to easily create a ggplot histogram with density curve in r using a secondary y axis.
Note that the default value of the argument stat is bin in this case the height of the bar represents the count of cases in each category.
Allowed value is a string containing any of trbl for top right bottom and left.
There will be a warning if any finite values are omitted but non finite values are omitted silently.
The function geom rug can be used.
Because of the way rug is implemented only values of x that fall within the plot region are included.
A string that controls which sides of the plot the rugs appear on.
All objects will be fortified to produce a data frame.
The rug and the confidence interval lines have been added by print plotgam which adds some default layers to empty plotgam objects.
Notice that plot gamviz returns an object of class plotgam which is initially empty the layers in the previous plots e g.
A marginal rug is a one dimensional density plot drawn on the axis of a plot.
It can be used to observe the marginal distributions more clearly.
Rug plots display individual cases so are best used with.
Create elegant data visualisations using the grammar of graphics.
Note you can as well add marginal plots to show these distributions.
A rug plot is a compact visualisation designed to supplement a 2d display with the two 1d marginal distributions.
This can be avoided by setting addlay false in the call to print plotgam.
Rug plots display individual cases so are best used with smaller datasets.
You can easily add rug on x and y axis thanks to the geom rug function to illustrate the distribution of dots.
Geom rug mapping null data null.
Add marginal rugs to a scatter plot.
If null the default the data is inherited from the plot data as specified in the call to ggplot.
A data frame or other object will override the plot data.
