X3D Scatter Plot Function of R
18.4.3
Using the
D coordinate system introduced above as a template, it is easy to create
a
D scatter plot by simply transforming the coordinates and plotting points using
a text editor. However, this is not easy when there are numerous data points to visu-
alize.
herefore, we provide a function that enables the statistical package R (R Project,
) to make a
D scatter plot. he options available for the
D scatter plot are
rescalingandpresentation ofthecoordinateaxes,coordinateplanes,frames,andcase
labels.Aninteractive functiontoshowthecasenameandthecoordinatesonthebot-
tomright-hand status bar whena point is selected is also implemented. hefunction
x3dplot3d()
can create a grouped scatter plot with colors (see Fig.
.
).
Applications
18.5
SVG Application as Teachware
18.5.1
As we mentioned in Sect.
.
, there is a great deal of sotware on the Webthat can be
used to teach statistical thinking or concepts. Since most students are familiar with
TV or games, it is mostproductive to teach statistics in an interactive and visual way.
his is the aim of statistical teachware such as MM*Stat (MD*Tech,
) and inter-
active textbooks like e-books (MD*Tech,
),including those provided by XploRe
(MD*Tech,
).
