+curve (r-SAC), which is the number of species represented at least r times as
+a function of the sampling effort.  When r = 1, the curve is known as the
+species accumulation curve, or the library complexity curve in high-throughput
+genomic sequencing.  The package includes both parametric and nonparametric
+methods, as described by Deng C, et al. (2018).")
