Dear all,
this is not strictly R question. I have two vectors of different length (this is in the order of 10%). I am trying to see if still one can compare these two for similarity.

IF the vectors were of the same length I would just take the difference of the two and plot a pdf of it.

One way I am thinking is prorbably to find the longer length and short it in some way to get to the length of the short. 


Which are the math formulations for this type of problems and which of those R supports?

Regards
Alex
