This paragraph says: Let bk = xmin+k·δ for k = 0,...,n, and wk = fw(bk +δ) for k = 0,...,n. However I believe that fw(bk) would be far more desirable. I strongly suspect that this is nothing but a type-o.

[ Resolution proposed by ballot comment: ]

Change p. 10 to read:
Let bk = xmin+k·δ for k = 0,...,n, and wk = fw(bk) for k = 0,...,n.

[ Adopted at 2010-11 Batavia ]

Proposed resolution:

Change [rand.dist.samp.plinear] p. 10 as indicated:

10 Effects: Constructs a piecewise_linear_distribution object with parameters taken or calculated from the following values: Let bk = xmin+k·δ for k = 0, . . . , n, and wk = fw(bk) for k = 0, . . . , n.
