Efficient rarefaction
vmikk opened this issue · comments
Need to implement efficient rarefaction function based on RTK.
Notes:
RTK performance and memory consumption was compared with vegan v.2.4 (Saary et al., 2017).
However, rarefaction was greatly improved in vegan v.2.5-1:
Random rarefaction (function rrarefy) uses compiled C code and is much faster.
