R factor is used to store categorical data as levels. It can store both character and integer types of data. These factors are created with the help of factor() 

rstudio data frame view  Factor variables are stored, internally, as numeric variables together with their levels. The actual values of the numeric variable are 1, 2, and so on. Not every level  The function factor is used to encode a vector as a factor (the terms 'category' and 'enumerated type' are also used for factors). If argument ordered is TRUE , the  f2 <- factor(c("b", "a")) fct_c(f1, f2) fct_unify(fs, levels = lvls_union(fs)) Standardize levels across a list of factors. fct_unify(list(f2, f1)).

Factor. Factor variables are a special case of character variables in the sense that it also contains text. However, factor variables are used when there are a limited number of unique character strings. It often represents a categorical variable.

A factor is an integer vector with a levels attribute that stores a set of mappings between integers and categorical values. When you view a factor, R displays not the integers, but the values associated with them. fct_c(…) Combine factors with different levels. f1 <- factor(c("a", "c")) f2 <- factor(c("b", "a")) fct_c(f1, f2) Recoding a categorical variable. The easiest way is to use revalue() or mapvalues() from the plyr package.
