Find and replace many factors in one column in R

I have column with 32 different levels. I need to replace these levels

 ?
 diet
 diet contr
 IDDM
 Note
 Other
 denial
 Resolved
 Unsure

in that column to No

I know I can do this using a massive ifelse((column = "?" | column = "diet" |.....) statement, i was wondering if there is an efficient way to do replace these bag of factors ?
