I'm wondering how to create a variable name (of a variable that already exist) using paste and then access this variable.

Example: 

```
var<-c("A","B","C")

for (i in 1:3){
     paste0("var")[i] 
}

```

*Note: Assume, that I need to use `paste0` to create the variable name (I'm dealing with data.frames and use `paste0` to create the variables for the different columns)*

Thanks!

EDIT:

Alright, here's the bigger picture:
I have two data frames: `smallDF` and `bigDF`. I want to copy data from bigDF to smallDF. Matching is done with the `user_name`.

```
user <- c("userA","userB","userC")
variables<-c("user_age","user_city","user_street")

for (t in 1:length(variables)){

  for (j in 1:length(user)){

    x<-paste0("bigDF$",variables[t])
    y<-paste0("smallDF$",variables[t])

    tmp<-unique(x[which(bigDF$user_name==user[j])])[1] # unique will only yield one entry
    replace<-c(as.character(rep(tmp,length(y[which(smallDF$user_name==user[j])]))))
    y[which(smallDF$user_name==user[j])]<-replace

  }
}

```

The code above does not work. However, when I avoid the first for-loop and replace x and y with the respective variable names (bigDF$user\_age etc) everything works. That's why I thought there must be a simple way of creating those variable names on the fly with the outer for-loop.
Thanks everybody!
