I'm trying to use lapply on my set of variables but I want the output as separate variables. For example.

```
df <- list(var1,var2,var3,var4)
di <- function(x) {diff(x)
difference <- lapply(df,di)

```

but this gives me a list of 4 items. but I want this result as x1,x2,x3,x4.
Is it possible to get this ?
Sorry for not being able to explain enough.
