Description Usage Arguments Details Value Note Author(s) Examples
We call a widget "dynamic" if it updates itself immediately when an event occurs, such as a drag and drop, or a change in some value. The dynamic widgets documented here, are meant to provide quick, easy (but limited) access to R's modeling functions, R's significance tests, and R's lattice functions

For each "dynamic" widget, the variables can be specified by
drag and drop, or by editing the widget. The bold-face areas
of each widget can be edited by clicking on them or by
dropping values. If the drop value comes from a column of an
idf
instance, then when that column is edited, the
dynamic widget is updated. Such variables can not be edited or
changed. Other variables may, such as writing powers, or
applying functions.
The "dynamic" widgets are meant for easy exploration, but not for saving of actions.
The dModelsDialog shows an interface to lm
, aov
,
and rlm
. The user can only specifiy formulas of the
type y ~ 1 + x1 + x2 + ... + xn
. Dropping a value on
"response" changes the response. Dropping a value on the right
side of the ~
adds the term (using +
). If the
terms are edited by clicking, the values are split on the +
sign.
For each model fit, a drop list allows one to generate several of the diagnostic plots.
The dTestsDialog
offers an interface to most of the
tests in the stats
package of class ctests
. (The
chisq.test
is not implemented yet.) Not only can
variables be dropped, but one can also change, as appropriate,
the choice of the null, the alternative, etc. Again, the
bold-face terms may be edited by clicking on them.
The ilatticeexplorer
function creates a dynamic
graphing widget based on lattice
graphics. Up to three
variables (only 2 for univariate graphs) may be dropped on the
widget. The order is for univariate graphs: ~x
then
~x | y
. And for bivariate graphs x
, x ~
y
, x ~ y | z
. The panel functions add to the plots of
dots by, typically, incorporating some trend line.
Although there are methods for dModelsDialog
, these
widgets aren't meant to be interacted with from the command line.
Some of the usability was inspired by the Fathom software.
