print.data.table row id in scientific notation #1167
Description
The row names while printing, in data.table the row id sequence, is printed in scientific notation. I wonder if it was like that all the time? or maybe it is something which came with 3.2.0?
It is some way confusing as does not distinct the row numbers.
library(data.table)
set.seed(1)
DT <- data.table(a = 1:5, b = letters[1:3], d = rnorm(5*3*1e6))
DT
