CHANGES IN spMC 0.3.2

  NEW FEATURES: 
    o pers.multi_tpfit() will produce perspective plots for 
      theoretical multidimensional transiograms.

    o perp.pemt() will produce perspective plots for 
      pseudo-empirical multidimensional transiograms.

    o sim(), sim_ck(), sim_ik(), sim_mcs() and sim_path() are now
      returning an object of class "data.frame" and "spsim".

    o tpfit(), tpfit_ml(), tpfit_ils(), tpfit_me(), multi_tpfit(),
      multi_tpfit_ml(), multi_tpfit_ils(), multi_tpfit_me(), mlen()
      and pemt() allows for the choice among serveral mean lengths 
      estimation method through the argument "mle".

    o transiogram() can also compute empirical probabilities for
      reversible chains throught the argument "reverse".

  UTILITIES:
    o Other robust methods are implemented for computing more
      reliable mean lengths. The choice can be perfrome among
      the averaging method ("avg"), the maximum likelihood estimator
      ("mlk"), trimmed average ("trm") or trimmed median ("mdn").

  DEPRECATED AND DEFUNCT:
    o the arguments GA, optype and max.it in functions sim_ik() and
      sim_ck() are deprecated. They will be considered defunct from
      next version release.
    
    o tpfit(mle = FALSE) is deprecated.

    o tpfit_ml(mle = FALSE) is deprecated.

    o tpfit_ils(mle = FALSE) is deprecated.

    o tpfit_me(mle = FALSE) is deprecated.

    o multi_tpfit(mle = FALSE) is deprecated.

    o multi_tpfit_ml(mle = FALSE) is deprecated.

    o multi_tpfit_ils(mle = FALSE) is deprecated.

    o multi_tpfit_me(mle = FALSE) is deprecated.

    o mlen(mle = FALSE) is deprecated.

    o pemt(mle = FALSE) is deprecated.

  BUG FIXES:
    o The polar transformation performed by the C procedure "nsph"
      was not much accurate, and computationally inefficient.

    o Memory bugs were fixed for C procedures "getCKPrbs", 
      "getIKPrbs", "nsph" and "transCount".

    o colors correspondence between transiograms and legend was fixed
      in functions image.multi_tpfit() and image.pemt().

CHANGES IN spMC 0.3.1

  NEW FEATURES:
    o tpfit_ml(), tpfit_ils(), tpfit_me(), multi_tpfit_ml(), 
      multi_tpfit_ils(), multi_tpfit_me() and other functions are
      introduced for R-methods consistency (see list of deprecated
      and defunct functions).

    o multi_tpfit() and tpfit() may perform all the other estimation
      methods by the use of the new argument method.

    o sim() may simulate and predict with all the available methods.

  UTILITIES:
    o contour.pemt() display contours of the pseudo-empirical 
      multidimensional and superpose the contour lines of the 
      theoretical transition probabilities.

    o image.pemt() plot the pseudo-empirical multidimensional 
      transiograms, which where previously computed.

    o is.pemt() tests an object if it is of the class 'pemt'.

    o pemt() returns pseudo-empirical multidimensional transiograms.

  DEPRECATED AND DEFUNCT:
    o ck.sim() is defunct. Use sim_ck() instead.

    o embed.MC() is defunct. Use embed_MC() instead.

    o ik.sim() is defunct. Use sim_ik() instead.

    o ilstpfit() and multi.ilstpfit() are defunct. 

      Iterated least squares are available by the use of the functions
      tpfit_ils() or multi_tpfit_ils().

    o image.multi.tpfit() is defunct. Use image.multi_tpfit() instead.

    o imgMultiTransiogram() is defunct.

      Pseudo-empirical multidimensional transiograms are now computed 
      first by the function pemt() and then plotted through 
      image.pemt().

    o is.multi.tpfit() is defunct. Use is.multi_tpfit() instead.

    o is.multi.transiogram() is defunct. Use is.multi_transiogram()
      instead.

    o mcs.sim() is defunct. Use sim_mcs() instead.

    o metpfit and multi.metpfit() are defunct.

      Maximum entropy methods is available by the use of the functions
      tpfit_me() or multi_tpfit_me().

    o multi.tpfit() is defunct.

      Multidimensional version of tpfit() is available by the use of
      the function multi_tpfit().

    o path.sim() is defunct. Use sim_path() instead.

    o predict.multi.tpfit() is defunct. Use predict.multi_tpfit()
      instead.

    o print.multi.tpfit() is defunct. Use print.multi_tpfit() instead.

    o print.multi.transiogram() is defunct. Use 
      print.multi_transiogram() instead.

    o which.lines() is defunct. Use which_lines().
