Dear all,

I have just uploaded to CRAN the version 1.3 of the
package 'adehabitat'. Significant changes are
listed below:

- Several functions allowing the conversion from
  and to classes of the package sp have been added.
  Maps of class "asc", "kasc", "area", as well as
  radio-monitoring of class "traj" can now be
  converted to the spatial classes available in sp.

- The function buffer.line() allows to compute buffer
  around a line

- The function distfacmap() converts one factor map
  into a set of maps giving the distance to the
  patches belonging to the different levels.

- The kernel home-range estimation can now be fitted
  using an Epanechnikov kernel (though it is still
  optional), resulting in a quicker estimation.

- The former function enfa() has been modified. It
  now requires a data frame (available units) and
  a vector (use of each unit). If the data consist
  of a point pattern and of an object kasc, the
  function data2enfa is to be used before.

- The function angles() now takes an argument
  indicating how successive relocations
  located at the same place have to be managed.

- The function as.traj now requires at least 2
  relocations to return a trajectory

- That's all, thanks for reading !

Questions, comments and suggestions are greatly appreciated.
Happy testing,
