What's New in version 2.15.1
  • source() now uses withVisible() rather than .Internal(eval.with.vis). This sometimes alters tracebacks slightly.
  • install.packages("pkg_version.tgz") on Mac OS X now has sanity checks that this is actually a binary package (as people have tried it with incorrectly named source packages).
  • splineDesign() and spline.des() in package splines have a new option sparse which can be used for efficient construction of a sparse B-spline design matrix (via Matrix).
  • norm() now allows type = "2" (the ‘spectral’ or 2-norm) as well, mainly for didactical completeness.
