rsba.alk-class: Class "alk" to define *a*sked *l*in*k* by the user

In rebastaba: Handling Bayesian networks

Description

Link was the former term for node, so asked link means asked node in the spirit that a user is defining a node to be incorporated to an already initiated /bn/. In fact there are two kinds of /alk/: either defined per se or fitted to a given /bn/ (for instance to take advantage of the parent properties). In the latter case, it is said completed and this is indicated with the @lcomp slot.

Objects from the Class

Objects can be created by calls of the form new("alk").

Slots

ldes:

Object of class "des": description of the /alk/

ltype:

Object of class "character": type(s) of the node variable(s)

lpara:

Object of class "list": parameters when parametric distribution of the variables

lrep:

Object of class "numeric": number of repeated variables of the node. Must be 0 when there are no repetitions.

lnat:

Object of class "character": natures of the node variables

lvar:

Object of class "character": variate names of the node (must be "" when only one implicit variable.

lparent:

Object of class "character": parents of the node.

lpod:

Object of class "list": maximal ranges for each variable of the node (lower and upper limit for numeric variables; all accepted values for categoric variables).

lred:

Object of class "list": like slot @lpod but defines the maximal ranges used in graphs.

lcod:

Object of class "list": like slot @lpod but defines the supposed common ranges of the variables (used for presentations).

ltransfo:

Object of class "character": easyprogramming defining the possible transformation to apply to all variables of the node.

ldaf:

Object of class "daf": when data based node defines the related data.frame to the definition of the node.

lwin:

Object of class "win": when data based node defined the way to perform the non parametric drawing.

lfunct:

Object of class "function": when user programmed node, is the function for random draws of the node.

lcomp:

Object of class "logical": indicates if the node is completed or not.
