		CHANGES IN animation VERSION 1.1-0


NEW FEATURES

    o three demos to illustrate recursion added: see 
  demo('recur.leaf'), demo('recur.snow') and
  demo('recur.tree'); thanks, Taiyun!
    o demo('Xmas') added

MINOR CHANGES

    o fixed a bug for the option 'interval': in the
  non-interactive environment, ani.start() and
  ani.stop() should use ani.options()$interval
  to obtain the REAL 'interval' (other than 0)
    o a new argument 'install.animate' for saveLatex()
  to install the LaTeX 'animate' if it does not exist
    o a new argument 'width.cutoff' for tidy.source()
  to decide the width of deparsed code
    o removed the code to install ImageMagick in
  saveMovie()
    o changed shell() to system() in saveMovie()
  (thanks, R. Woodrow Setzer)
    o updated the LaTeX package 'animate'

    
TO APPEAR 
    
    o A function boot.loess() added to show the
  bootstrapping effects on loess().
    o A function cart.ani() to show the splitting
  process of classification and regression trees.
    o Yixuan is working on porting SWF Tools into
  R.

NEW FEATURES

    o a new function MC.hitormiss() to demonstrate
  the 'hit or miss' Monte Carlo integration
    o a new function MC.samplemean() to demonstrate
  the 'sample mean' Monte Carlo integration
    o a new function price.ani() to demonstrate 
  the stock prices changing within a time span
  (inspired by Shen Dai)

MINOR CHANGES

    o we can specify the 'convert' command in 
  saveMovie(); e.g. 'imconvert' under some Windows
  platforms (Thanks, James Pustejovsky)

		CHANGES IN animation VERSION 1.0-9


NEW FEATURES

    o saveLatex() to embed the animation into a
  LaTeX document (with LaTeX package 'animate').
    o a new option 'imgdir' added to ani.options()
  so that users can specify the name of the image 
  directory
    o a message will come up if the animation option
  'nmax' is changed; this will help users know the
  actual number of images in the current session;
  this message will only show in interactive mode
    o saveMovie() will try to install ImageMagick
  automatically if 'convert' not found

MINOR CHANGES

    o query ani.options('interval') will return 0 if
  the animation is run in a non-interactive mode;
  this will save much time typically in 'R CMD check'
  (Thanks to Prof Ripley)
    o the option 'nmax' will be adjusted to the 
  *actual* number of images in the directory 
  ani.options('imgdir'), because sometimes the actual
  number of images does not equal to ani.options('nmax')
    o shortened the descriptions in Rd files and 
  several changes in documentations 
    o fixed several buglets in ani.stop()
    o changed the 'while' loop to 'for' loop in
  brownian.motion(); this will shorten the code by
  two lines
    o ani.options('ani.dev') can be the name of a
  function (character), e.g. "png"

		CHANGES IN animation VERSION 1.0-7


NEW FEATURES

    o moving.block() to plot a subset of data by blocks
    o ani.options() gained a new argument 'loop' to 
  control the iteration of the animation in an HTML
  page: TRUE to interate for infinite times, and FALSE
  not to interate (only play once). Thanks, Marcin Kozak!

MINOR CHANGES

    o fixed a bug for in ani.stop(): when 
  ani.options(footer = FALSE), ani.stop() will report
  an error for non-existent object 'footer'; I should
  have used the value ani.options("footer") in the code.
  Thanks, Marcin Kozak!

  a custom string to be written in the HTML page
  as the footer information. (Thanks, Jorge Nieves)

SIGNIFICANT CHANGES

    o tidy.source2() was merged into tidy.source(),
  and tidy.source() now returns a list of character
  vectors and also gains an argument 'output' to 
  decide whether to output the tidied code (to 
  R console or a file).

  Galton box or Bean Machine. (Thanks for the 
  inspiration from Roger Koenker)

  to independent sample means instead of the original
  'cumulative' data. (Thanks, Duncan Murdoch)
    o Arguments 'col.contour' and 'col.arrow' added
  to grad.desc() to specify the colors for the contour
  lines and arrows freely; the graphical parameters
  are no longer specified within the function using
  par().
    o The path of SWF Tools in saveSWF() will be 
  quoted by shQuote() instead of dQuote(). 
  (Thanks, zhoulvjun)

		CHANGES IN animation VERSION 1.0-0


NEW FEATURES

    o ani.options() added to control animation parameters.
  It is much better than ani.control() in previous
  versions.
    o ani.start() and ani.stop() are modified. The former
  function opens a graphics device and the latter one
  create an HTML page with a new interface.
    o A wiki has been build to support this package:
  http://animation.yihui.name (AniWiki: Animations in
  Statistics)

MINOR CHANGES

    o Graphical parameters can be set in ... argument for:
  brownian.motion(), buffon.needle(), clt.ani(), conf.int(),
  cv.ani(), lln.ani(), mwar.ani(), newton.method(),
  sample.cluster(), sample.strat().
    o P-values are computed in clt.ani() to check the
  normality (using 'shapiro.test()').

SIGNIFICANT CHANGES

    o The vignette is abandoned and stopped being updated;
  the wiki http://animation.yihui.name will be used instead.
    o The way to create HTML animations is significantly
  changed for the sake of a better interface and more
  flexible control of animations. Read the help files 
  for ani.control(), ani.start(), ani.stop().
    o The function savePNG() removed. The new way to
  create animation frames allows ANY graphics devices.
    o ani.control() and checkargs() removed. The new
  way to control animation parameters is more flexible.

  cross-validation to find the optimum number of features
  in LDA. 

MINOR CHANGES

  kmeans.ani() so that the moving of centers can be
  better observed.

  better illustrations for the CLT.

    o A special function checkargs() is added to validate 
  animation arguments, which can promote the efficiency 
  of animation functions.

  marked out in later steps of classification for the rest points.
    o The values of PI are silently returned in buffon.needle().

  we do cross-validation, the splitting of trainig set and test set
  will change (instead of splitting 1:n into k parts). The tick 
  marks of x-axis will change accordingly.
