R help - Jun 2010 - Unique Data Frame Name?

Hello,

I am trying to create a data frame with a unique name, based on indexing 
of for loop.  I was wondering if there is a way to do this, I keep 
running into errors when I try to do this.  Below is a brief example, I 
am trying to get two data frames (name1 and name2).

Any suggestions are appreciated.

Thanks,
Doug

# Example
for (i in 1:2) {
        x=c(1,2,3,4)
        y=c(10,20,30,40)
        G <- paste("name", i, sep="")
        G[i] <- data.frame(x,y)
}

\Why not put all the data frames in a list?

Hi:

Try this:
> for (i in 1:2) {
+       x=c(1,2,3,4)
+       y=c(10,20,30,40)
+       G <- paste("name", i, sep="")
+       assign(G, data.frame(x,y))
+ }
> name1
  x  y
1 1 10
2 2 20
3 3 30
4 4 40
> name2
  x  y
1 1 10
2 2 20
3 3 30
4 4 40


HTH,
Dennis
