Overlap two variable

Question

[skjobs]

I have two variable (A) and (B). I want to cover the maximum alignment overlap using both variables (A) and (B) which is nearly 100. This is my input is like that

ID       Variable_A    Variable_B
PDD1         9             42
PDD2         34            60
PDD3         70            90
PDD4         50            100

So, I want to cover the maximum number range in this variables. My desire output like this

PDD1
PDD2
PDB4

Could you rephrase your question please ? and define how Variable_A and _B are overlap ? and also what are the values in the dataframe ?

I think "PDD3 70-90" is already covered by "50-100", so it drops off.

Might be a job for GenomicRanges::reduce().
