As you are aware, you can only perform the "cor" operation on numbers. As the value returned refers to the correlation of _pairs_ of values, the vectors of numbers should be the same length and there should be some meaningful relationship between those pairs. Are you just trying to correlate any old numbers because they are numbers?

Maybe one day we will find out what is in: coding.rpkm ncoding.rpkm and we can provide more informed advice.
