[R] How to Create Nested Data Frame

[Gundala Viswanath]

Hi Ivan,

Thanks for the reply.

But I won't do.

> names(dat1) <- names(dat2) <- c("labels","predictions")
> HIV <- list(hiv.dat1=dat1, hiv.dat2=dat2)


The above snippet produces this instead:

> names(dat1) <- names(dat2) <- c("labels","predictions")
> HIV <- list(hiv.dat1=dat1, hiv.dat2=dat2);
>
> print(HIV)
$hiv.dat1
  labels predictions
1      1          43
2      1          43
3      1          43

$hiv.dat2
  labels predictions
1      1          43
2      1          21
3      1          43
4      1          43
5      1          24
6      0          24
