For instances where the desired value is unknown either the instance may be dropped, or missing values used.<p> Valid filter-specific options are:<p> -R index1,index2-index4,...<br> Specify list of columns to calculate new values for. First and last are valid indexes. (default none)<p> -V <br> Invert matching sense (i.e. calculate for all non-specified columns)<p> -I num <br> The number of instances forward to merge values between. A negative number indicates taking values from a past instance. (default -1) <p> -M <br> For instances at the beginning or end of the dataset where the translated values are not known, remove those instances (default is to use missing values).
