[R] factor names

[Iasonas Lamprianou]

Dear all
I have a factor variable which holds values like "Engineer", "Doctor", "Teacher" 
etc. I would like to collapse those categories so that Teachers and Sociologists 
form one category named "Teach & Soc" etc. However, I do not know how I can do 
it. Recoding does not seem to work. 

Thank you
 Dr. Iasonas Lamprianou
