The |
names |
List of names of attributes to be normalized. For more information see |
oper |
The code giving the type of normalization to be performed:
|
center |
Defines the value for the mean of the normalized variable (if provided). Otherwise it will be set to 0. |
stdv |
Defines the value for the standard deviation of the normalized variable (if provided). Otherwise it will be set to 1. |
radix |
Radix of the name given to the variables storing the results in the target Db. |
modify.target |
Decides whether or not the newly created variables will have their

flag.replace |
When TRUE, each initial variable is replaced by the corresponding modified variable |
