reducepoly has an optional input "tolerance" which is a number in the range [0,1]. Is there a way to specify the absolute tolerance or another way to achieve this?

Hi Margaret,
According to the documentation, the only way to specify the absolute tolerence ( maximum reduction in points) is by keeping it 1.
Hope it helps

I meant absolute tolerance as opposed to relative tolerance. That is, I wanted to reduce the number of points on the curve while keeping the reduced curve within epsilon of the original. It is not clear what value of epsilon the tolerance parameter in the function corresponds to, though I assume it is something like tolerance*range.
I solved this by implementing Ramer–Douglas–Peucker algorithm on my own.
