rp.gulls
(Package: rpanel) :
STEPS module: the Birds and the Bees
The function launches a panel which contains an image of a herring gull. With this bird, sex cannot easily be identified by visual inspection. The user is invited to identify length measurements, defined by pairs of landmarks, which will enable males and females to be identified.

rp.menu
(Package: rpanel) :
Top level menu for a panel
This function adds a menu to the top of the panel window. When a menu item is selected, a variable is set and an action function is called.

rp.logistic
(Package: rpanel) :
Interactive display of logistic regression with a single covariate
The function rp.logistic plots a binary or binomial response variable against a single covariates and creates a panel which controls the position of a logistic curve and allows a logistic regression to be fitted to the data and displayed on the plot.

gullweight
(Package: rpanel) :
The weights of herring gulls captured at different times of year
These data are part of a large sample collected by Prof. P. Monaghan of the University of Glasgow in a study of the weight changes in herring gulls throughout the year. Some birds were caught in June (coded as month 1) and others in December (month 2). Since weight is dependent on the size of the bird this information is recorded in the form of the head and bill length, hab (in mm), the distance from the back of the head to the tip of the bill.

rp.radiogroup
(Package: rpanel) :
Radiobuttons for a panel
This function adds a set of radiobuttons to the panel. When a radiobutton is pressed, a variable is set and an action function is called.

rp.power
(Package: rpanel) :
Interactive power calculations for a two-sample t-test
This function creates a panel which allows the sample size, population means and common standard deviation to be set. The correponding power curve for a two-sample t-test is displayed in the graphics window.

CranContrib
● Keywords: dynamic, iplot

rp.regression
(Package: rpanel) :
Interactive display of regression with one or two covariates
The function rp.regression plots a response variable against one or two covariates and creates a panel which controls the model which is fitted to the data and displayed on the plot. In the case of two covariates, a three-dimensional display is created. The function rp.regression2 is retained simply for compatibility with earlier releases of the package.

rp.combo
(Package: rpanel) :
A `combo' for a panel
This function adds a ‘combobox’ to the panel. When an item is pressed, a variable is set and an action function is called.

rp.var.get
(Package: rpanel) :
Retrieves an object from the rpanel envrionment, usually from a panel.
The management of objects within the rpanel environment is usually handled ‘behind the scenes’ but it can occasionally be useful to retrieve an object there explicitly.

rp.firth
(Package: rpanel) :
Geostatistical sampling and analysis simulation tool
This function gives access to a sampling scenario which is based on the mapping of radioactivity and the calculation of a radionuclide inventory within a water body. (A ‘firth’ is a Scottish term for a long, narrow indentation of the sea coast at the mouth of a river.) Interest lies in nuclides which, on release into a water body, attach (absorb) to sediment in a manner which depends on the sediment particle size. Cobalt-60 and caesium-137 are examples of nuclides which exhibit this behaviour. In this sampling scenario, the map of sediment type is used to define regions of different particle size from which the sediment samples will be collected by grabs from a boat. The presence of strata therefore has to be considered, as the different types of material on the sea bed may affect the mean values of the measurements taken.
