If I have a dataset called data.
I need to add a column based on this logic 0 if "gender" in data is 0 or 1 or 3; 1 if "gender" in data is 2
How can I create a code to add in?

Assuming gender would only take on the possible values 0, 1, and 2, we can try using ifelse as follows:
data$flag <- ifelse(data$gender <= 1, 0, 1)
We can use case_when() from the dplyr library for finer grain control:
data$flag <- case_when(
gender %in% c(0, 1) ~ 0,
gender == 2 ~ 1,
# add other mappings here
TRUE ~ NA
)
