Hello,
I call function findInterval in the following way:
findInterval(x=c(6, 1, 1, 1), vec=c(0, 1, 3, 5, 10), left.open=TRUE),
and expect that it will return 4 1 1 1. But the function returns 4 2 1 1
instead. Moreover, if I change the first element in x to, say, 4 -
findInterval(x=c(4, 1, 1, 1), vec=c(0, 1, 3, 5, 10), left.open=TRUE)
then the function returns 3 1 1 1.
Why are results for identical elements in x not the same? And why is element in
x influenced by previous one? I suspect this is a bug but I am not 100% sure.
