IRanges::IntegerList & min / max #5
Description
Hi Michael @lawremi, Hervé @hpages,
A (recent?) change to IRanges IntegerList returns some unexpected results.
In base R, the min(integer()) returns Inf.
When taking the min or max of IRanges::IntegerList, you get the max integer
value in R (see below).
Should this match what base R returns?
