Virtual superclass for controlling the insertion of missing values in a simulation experiment.

A virtual Class: No objects may be created from it.

`target`

:A character vector specifying the variables (columns) into which missing values should be inserted, or

`NULL`

to insert missing values into all variables (except additional ones generated internally).`NARate`

:A numeric matrix giving the missing value rates. In case of only one column, the same missing value rates are used for all target variables. Otherwise the missing value rates to be used for each target variable are given by the respective column. A vector is converted to a matrix during initialization.

Class `"OptNAControl"`

, directly.

`getTarget`

`signature(x = "VirtualNAControl")`

: get slot`target`

.`getNARate`

`signature(x = "VirtualNAControl")`

: get slot`NARate`

.

`head`

`signature(x = "VirtualNAControl")`

: currently returns the object itself.`length`

`signature(x = "VirtualNAControl")`

: get the number of missing value rates to be used (i.e., the number of rows).`show`

`signature(object = "VirtualNAControl")`

: print the object on the**R**console.`summary`

`signature(object = "VirtualNAControl")`

: currently returns the object itself.`tail`

`signature(x = "VirtualNAControl")`

: currently returns the object itself.
