a character vector containing the names of variables of type
mixed (semi-continous).
method
Method used for Initialization (median or kNN)
mixed.constant
vector with length equal to the number of
semi-continuous variables specifying the point of the semi-continuous
distribution with non-zero probability
Details
Missing values are imputed with the mean for vectors of class
"numeric", with the median for vectors of class "integer", and
with the mode for vectors of class "factor". Hence, x should
be prepared in the following way: assign class "numeric" to numeric
vectors, assign class "integer" to ordinal vectors, and assign class
"factor" to nominal or binary vectors.
Value
the initialized vector.
Note
The function is used internally by some imputation algorithms.
