Hi,

I have an issue concerning plyr.
I have a list l as output from dlply.

> l
$`1`
     (0.5,1.5] (1.5,2.5] (2.5,3.5]  (3.5,4.5]
f5_9 0.2342569  0.465995 0.2518892 0.04785894

attr(,"split_type")
[1] "data.frame"
attr(,"split_labels")
  f15
1   1

When I convert it into a dataframe I get.

> list_to_dataframe(l)
  .id X.0.5.1.5. X.1.5.2.5. X.2.5.3.5. X.3.5.4.5.
1   1  0.2342569   0.465995  0.2518892 0.04785894

The column labels have names I do not want.
When I do the same using two list elements everything is fine, that is column names are as desired.

> l2 <- c(l,l)
> list_to_dataframe(l2)
  .id (0.5,1.5] (1.5,2.5] (2.5,3.5]  (3.5,4.5]
1   1 0.2342569  0.465995 0.2518892 0.04785894
2   1 0.2342569  0.465995 0.2518892 0.04785894

Does someone know a remedy?

TIA,
Mark
