I have survey data that I have read into my R file. How do I define variables for multiple data points that are meant to be in the same category? I.e. for the Gender column I have: "M", "male", "Male", "Guy", etc. I want to have Male= "M", "male", "Male", "Guy". Thank you for your help in advance!

Assuming that the column is character class, we can use %in% to create a logical index to replace these values with a new one

df1$Col[df1$Col %in% c("M", "male", "Guy")] <- "Male"
