Add rug plot ggplot.
In this article you will learn how to easily create a ggplot histogram with density curve in r using a secondary y axis.
Allowed value is a string containing any of trbl for top right bottom and left.
Rug plots display individual cases so are best used with.

A rug plot is a compact visualisation designed to supplement a 2d display with the two 1d marginal distributions.
A data frame or other object will override the plot data.
A string that controls which sides of the plot the rugs appear on.
By using geom rug you can add marginal rugs to your scatter plot.
Which plots only the smooth effects diplaying one on each page.
Rug plots display individual cases so are best used with smaller datasets.
Because of the way rug is implemented only values of x that fall within the plot region are included.
Notice that plot gamviz returns an object of class plotgam which is initially empty the layers in the previous plots e g.
The function geom rug can be used.
The rug and the confidence interval lines have been added by print plotgam which adds some default layers to empty plotgam objects.
We ll use the ggpubr package to create the plots and the cowplot package to align the graphs.
A marginal rug is a one dimensional density plot drawn on the axis of a plot.
Description usage arguments details aesthetics examples.
Create elegant data visualisations using the grammar of graphics.
Note you can as well add marginal plots to show these distributions.
All objects will be fortified to produce a data frame.
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.
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.
This can be avoided by setting addlay false in the call to print plotgam.
There will be a warning if any finite values are omitted but non finite values are omitted silently.
Geom rug mapping null data null.
It can be used to observe the marginal distributions more clearly.
You can easily add rug on x and y axis thanks to the geom rug function to illustrate the distribution of dots.
