[R] Creating Dummy Var in R for regression?

[Shivi Bhatia]

Dear Team,

I need help with the below code in R:

gender_rec<- c('Dr','Father','Mr'=1, 'Miss','MS','Mrs'=2, 3)

reasons$salutation<- gender_rec[reasons$salutation].

This code gives me the correct output but it overwrites the
reason$salutation variable. I need to create a new variable gender to
capture gender details and leave salutation as it is.

i tried the below syntax but it is converting all to 1.

reasons$gender<- ifelse(reasons$salutation== "Mr" & reasons$salutation==
"Father","Male", ifelse(reasons$salutation=="Mrs" & reasons$salutation==
"Miss","Female",1))

Please suggest.
