# quick example of mutate (in the dplyr R package) to create a dummy variable

# packages (from the tidyverse)
library(tibble)
library(dplyr)

# a little tibble with an ID number and a gender variable (5 Female, 3 Male, 2 Not Stated)
mydata <- tibble(id = 1:10, gender = c("F", "F", "F", "F", "F",
                                       "M", "M", "M", 
                                       "NS", "NS"))

# create dummy variable for modeling, where Female = 1 and all others = 0
mydata %>%
  mutate(dummy = ifelse(gender == "F", 1, 0))
