The numerical summary methods always return integer64
.
Therefor the methods for min
,max
and range
do not return +Inf,-Inf
on empty arguments, but +9223372036854775807, -9223372036854775807
(in this sequence).
The same is true if only NA
s are submitted with argument na.rm=TRUE
.
lim.integer64
returns these limits in proper order -9223372036854775807, +9223372036854775807
and without a warning
.
