gratia version 0.5.1 now on CRAN

This release was prompted by an issue with an argument naming choice in the new smooth_estimates() function. Some additional functionality was completed prior to realising I needed to release 0.5.1,

User visible changes

• The newdata argument to smooth_estimates() has been changed to data as
  was originally intended.

New features

• smooth_estimates() can now handle

  • bivariate and multivariate thinplate regression spline smooths, e.g.
    s(x, z, a),
  • tensor product smooths (te(), t2(), & ti()), e.g. te(x, z, a)
  • factor smooth interactions, e.g. s(x, f, bs = "fs")
  • random effect smooths, e.g. s(f, bs = "re")

• penalty() provides a tidy representation of the penalty matrices of
  smooths. The tidy representation is most suitable for plotting with
  ggplot().

  A draw() method is provided, which represents the penalty matrix as a
  heatmap.
