  • Changed explanation of proj_dist function

  • fix missing export for proj_dist

  • minor example fix for ggplot2 0.9 compatibility

  • display_density correctly displays axis labels

  • cm was renamed to cmass; the dataset sleep was removed
  • search_geodesic was passing the wrong parameter to find_best_dir causing it to search very far away instead of very close, and negatively impacting performance (thanks to Mohit Dayal for reporting the bug)
  • move ggplot2 from depends to suggests
  • add CITATION to JSS paper
  • export find_platform function
  • small fixes for compatibility with the tourrGui package.
  • change documentation file name for nul to avoid problems in Windows 7 (thanks to Brian Ripley)
  • many bug fixes in tour algorithms, interpolation and history saving

  • animate now invisibly returns the bases it displayed when it terminates

  • tourr now has better NAMESPACE so should play better with other packages

  • display_xy and display_dist do a better at guessing the display range

  • new display_trails rendering

  • display_dist gains a rug option
