The Difference Between Factor and Ordered Factor in R

In R language, a factor is a data type used to categorize and store non-numeric data. It assigns levels to distinct categories in a variable. On the other hand, an ordered factor is a subtype of factor that includes an inherent order among its levels. This means that the levels in an ordered factor have a specific sequence or rank.

While a factor simply represents categorical data without any implied order, an ordered factor includes a predefined order among its levels, making it suitable for ordinal data.

Overall, the key difference between factor and ordered factor in R is the presence of a specified order among the levels of the latter, providing additional information about the relationship between the categories.
