How do I convert a value to numeric in R?
Step 1: Convert the data vector into a factor. The factor() command is used to create and modify factors in R. Step 2: The factor is converted into a numeric vector using as. numeric() .
How do you convert to ordinal in R?
The factor() function also allows you to assign an order to the nominal variables, thus making them ordinal variables. This is done by setting the order parameter to TRUE and by assigning a vector with the desired level hierarchy to the argument levels .
