| VirtualNAControl-class {simFrame} | R Documentation |
Virtual superclass for controlling the insertion of missing values in a simulation experiment.
A virtual Class: No objects may be created from it.
target:"OptCharacter"; a character
vector specifying the variables (columns) in which missing values should
be inserted, or NULL to insert missing values in all variables
(except the additional ones generated internally).NArate:"NumericMatrix" giving the
missing value rates, which may be selected individually for the target
variables. In case of a vector, the same missing value rates are used for
all target variables. In case of a matrix, on the other hand, the missing
value rates to be used for each target variable are given by the
respective column.
Class "OptNAControl", directly.
signature(x = "VirtualNAControl"): get the number of
missing value rates to be used (the length in case of a vector or the
number of rows in case of a matrix).Andreas Alfons, alfons@statistik.tuwien.ac.at
