+     "For distributions whose probability density functions are log-concave,
+the adaptive rejection sampling algorithm can be used to build envelope
+functions for sampling.  For others, the modified adaptive rejection sampling
+algorithm, the concave-convex adaptive rejection sampling algorithm, and the
+adaptive slice sampling algorithm can be used.  This R package mainly includes
+these four functions: @code{rARS()}, @code{rMARS()}, @code{rCCARS()}, and
+@code{rASS()}.  These functions can realize sampling based on the algorithms
+above.")
