Hadley,

thanks for the quick reply:

list(structure(c(0.182198327359618, 0.473715651135006, 0.29689366786141,
0.0471923536439665), .Dim = c(1L, 4L), .Dimnames = list("f5_9",
    c("(0.5,1.5]", "(1.5,2.5]", "(2.5,3.5]", "(3.5,4.5]"))))

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
