How to handle INT8 data
Hello r users,
I have to deal with int8 data with R. AFAIK R does only handle int4
with `as.integer` function [1]. I wonder:
1. what is the better approach to handle int8 ? `as.character` ?
`as.numeric` ?
2. is there any plan to handle int8 in the future ? As you might know,
int4 is to small to deal with earth population right now.
Thanks for you ideas,
int8 eg:
human_id

TRUE
Which makes joining or grouping data sets with 64 bit identifiers
problematic.
