[R] find and replace

[arun]

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
#3 303  Julie California/New York City
#4 304 Monica            New York City
