plotConditional: Plot Conditional Functions

In MoTBFs: Learning Hybrid Bayesian Networks using Mixtures of Truncated Basis Functions

Plot Conditional Functions

Description

Plot conditional MoTBF densities.

Usage

plotConditional(
  conditionalFunction,
  data,
  nameChild = NULL,
  points = FALSE,
  color = NULL,
  ...
)

Arguments

conditionalFunction	the output of function conditionalMethod. A list containing the the interval of the parent and the final conditional density (MTE or MOP).
data	An object of class data.frame, corresponding to the dataset used to fit the conditional density.
nameChild	A character string, corresponding to the name of the child variable in the conditional density. By default, it is NULL.
points	A logical value. If TRUE, the sample points are overlaid.
color	If not specified, a default palette is used.
...	Additional graphical parameters passed to filled.contour().

Details

If the number of parents is greater than one, then the error message "It is not possible to plot the conditional function." is reported.

Value

A plot of the conditional density function.

Examples

## Data
X <- rnorm(1000)
Y <- rnorm(1000, mean=X)
data <- data.frame(X=X,Y=Y)
cov(data)

## Conditional Learning
parent <- "X"
child <- "Y"
intervals <- 5
potential <- "MTE"
P <- conditionalMethod(data, nameParents=parent, nameChild=child, 
numIntervals=intervals, POTENTIAL_TYPE=potential)
plotConditional(conditionalFunction=P, data=data)
plotConditional(conditionalFunction=P, data=data, points=TRUE)
