[R-Forge #5408] as.data.table.table creates names in an incorrect order #43
Description
Submitted by: Benjamin Barnes; Assigned to: Arun ; R-Forge link
The names of the resulting data.table are in the incorrect order. For example,
set.seed(123)
DT <- data.table(XX = sample(LETTERS[1:5], 1000, replace = TRUE),
yy = sample(1:5, 1000, replace = TRUE))
as.data.table(DT[, table(XX, yy)])
## Names are c("yy", "XX", "N")
## Should be c("XX", "yy", "N"), as in as.data.frame
