Replace contents of factor column in R dataframe

Question

I need to replace the levels of a factor column in a dataframe. Using the iris dataset as an example, how would I replace any cells which contain virginic

Answer 1

Using dlpyr::mutate and forcats::fct_recode:

library(dplyr)
library(forcats)

iris <- iris %>%  
  mutate(Species = fct_recode(Species,
    "Virginica" = "virginica",
    "Versicolor" = "versicolor"
  )) 

iris %>% 
  count(Species)

# A tibble: 3 x 2
     Species     n
       
1     setosa    50
2 Versicolor    50
3  Virginica    50
