splines2 0.2.2

Bug fixes

• Fixed the NA's handling in all the functions constructing spline bases.

splines2 0.2.1

New features

• Added function bSpline generating B-spline basis allowing zero degree or
  piecewise constant basis based on function bs in package splines.
• Introduced function bSpline to allow M-splines of degree zero.
• Added function cSpline constructing convex spline (C-spline) basis.
• Added predict methods for bSpline2 object and cSpline object generated
  by bSpline and cSpline, respectively.
• Added print methods for all splines2 objects developed so far.

Major changes

• Improved the function iSpline to construct I-spline basis directly from
  B-spline basis instead of M-spline basis.

Minor changes

• Updated all CRAN URL to a canonical form suggested.

splines2 0.1.0

New features

• The first version of splines2 providing functions constructing M-spline,
  I-spline, and integral of B-spline basis.
