[R] RArcInfo 0.4-2 and tutorial (draft) available

[Virgilio.Gomez@uv.es]

Hi,

 A new release of RArcInfo is avaialable from CRAN and
http://matheron.uv.es/~virgil/Rpackages/RArcInfo/

The changes made are:

*V 0.4-2
	- 'index' argument added to plotarc to select the arcs to plot.
	- 'index' argument added to plotpal to select the polygons to plot.
	- New function 'get.nb', which, given a set of polygons, returns
	the neighbouring polygons of each one.
	- Fixed a bug in 'get_tol_data'. The file to be open was of
	type CNT instead of TOL. Now tolerances are read without problems.
	- Output messages have been changed in several functions to
	be more useful for the user.
	- Fixed a bug in 'plotarc' when calculating plot dimensions.
	- Example added to RArcInfo documentation file.

Besides, I am proud to announce that a draf of the RArcInfo tutorial
is now available from http://matheron.uv.es/~virgil/Rpackages/RArcInfo/

I am looking forward to your comments.

REgards,

VIrgilio
