Answer 1

Answer:

Step-by-step explanation:Convert Factor to Numeric and Numeric to Factor in R Programming

Factors are data structures which are implemented to categorize the data or represent categorical data and store it on multiple levels.

They can be stored as integers with a corresponding label to every unique integer. Though factors may look similar to character vectors, they are integers, and care must be taken while using them as strings.

The factor accepts only a restricted number of distinct values. It is helpful in categorizing data and storing it on multiple levels.

Converting Factors to Numeric Values

At times you require to explicitly change factors to either numbers or text. To achieve this, one has to use the functions as.character() or as.numeric(). There are two steps for converting factor to numeric:

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().

When a factor is converted into a numeric vector, the numeric codes corresponding to the factor levels will be returned.
