Warning message:
inaccurate integer conversion in coercion
Why is the "10 billions as a string" case treated differently?
(coerced to INT_MAX-1)
And for the "minus 10 billions as a string" case, is the warning
message really appropriate? Why isn't it just the usual "NAs
introduced by coercion"?
Thanks,
H.
