Run some simple preprocessing of ordered categorical variables, converting ordered levels to integers if necessary, and storing the unique levels of a variable.

Run some simple preprocessing of ordered categorical variables, converting ordered levels to integers if necessary, and storing the unique levels of a variable.

Usage

orderedCatInitializeAndPreprocess(x_input)

Arguments

x_input

Vector of ordered categorical data. If the data is not already stored as an ordered factor, it will be converted to one using the default sort order.

Value

List containing a preprocessed vector of integer-converted ordered categorical observations and the unique level of the original ordered categorical feature.

Examples

x <- c("1. Strongly disagree", "3. Neither agree nor disagree", "2. Disagree", "4. Agree", "3. Neither agree nor disagree", "5. Strongly agree", "4. Agree")
preprocess_list <- orderedCatInitializeAndPreprocess(x)
x_preprocessed <- preprocess_list$x_preprocessed
