This can be avoided by setting addlay false in the call to print plotgam.
Add rug plot r.
Add a rug to a plot description.
Positive lengths give inwards ticks.
The line width of the ticks.
A marginal rug plot is essentially a one dimensional scatter plot that can be used to visualize the distribution of data on each axis.
Since the default scale expansion of for continuous variables is 5 at both ends of the scale the rug will not overlap with any data points under the default settings.
Plot ozone solar r data airquality however these measurements happen to include some missing values which are omitted from the scatter plot but could be informative.
1992 statistical models in s.
The colour the ticks are plotted in.
1992 statistical models in s.
Normally 1 bottom or 3 top.
Some devices will round the default width up to 1.
By default the rug lines are drawn with a length that corresponds to 3 of the total plot size.
Add a rug to a plot.
Because of the way rug is implemented only values of x that fall within the plot region are included.
Like a strip plot it represents values of a variable by putting a symbol at various points along an axis.
The rug and the confidence interval lines have been added by print plotgam which adds some default layers to empty plotgam objects.
On which side of the plot box the rug will be plotted.
It is a one dimensional display that you can add to existing plots to illuminate information that is sometimes lost in other types of graphs.
Adds a rug representation 1 d plot of the data to the plot.
There will be a warning if any finite values are omitted but non finite values are omitted silently.
However it uses short lines to represent.
The length of the ticks making up the rug.
Adds a rug representation 1 d plot of the data to the plot.
The rug is not really a separate plot.
In this particular data set the marginal rug is not as informative as it could be.
There will be a warning if any finite values are omitted but non finite values are omitted silently.
One common approach to include them in the plot is by adding marginal rugs after the main scatter plot has been plotted.
Notice that plot gamviz returns an object of class plotgam which is initially empty the layers in the previous plots e g.
