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
# ID Name Fav_Place
#1 101 Andrew Tucson AZ
#2 201 John San Francisco
