HI,
You can also try this:
Students1<-data.frame(ID=c(101,201,303,304),Name=c("Andrew","John","Julie","Monica"),Fav_Place=c("Phoenix AZ","San Francisco","California/New York","New York"))
?
gsubfun<-function(pattern,replacement,x, ...){
?for(i in seq_along(pattern))
?x<-gsub(pattern[i],replacement[i],x,...)
?x
?}
toreplace<-c("Phoenix","New York")
replacedwith<-c("Tucson","New York City")
Students1$Fav_Place<-gsubfun(toreplace,replacedwith,Students1$Fav_Place)
Students1
