Log Message:
(geography/R-deldir) Updated 0.1.28 to 1.0.6, make test passed

 Version 1.0-6 23/10/2021

 Fixed a bug that kept deldir() from working when "x" is a
 point pattern.

 Version 1.0-5 10/10/2021

 Changed the protocol for "digging out" x and y, and
 "digging out" z.  The rule now is: if the specified argument
 is found (located in the global environment, or given explicitly)
 then *use* it!  Only if it is *not* found elsewhere should it be
 sought in the "x" argument.  (This change was implemented after
 Duncan Murdoch convinced me to see the error of my previous ways.)

 Adjusted/corrected the processing of generic lists, as the x
 argument, in deldir()

 Re-wrote the discussion of the argument processing protocol in
 deldir.Rd, so as to make it properly reflect the current behaviour
 of the function.  It is also hoped that the clarity of the
 discussion has been improved.

 Fixed various glitches and typos in the code and the help files.

 Version 1.0-4 06/10/2021

 Fixed more bugs in deldir() w.r.t. argument processing, again
 pointed out to me by Duncan Murdoch.

 Fixed a bug in triang.list(); it crashed if there were not
 any actual triangles in the "triangulation"!

 Made an adjustment to plot.triang.list() (added an argument to
 specify a colour for the enclosing rectangle.

 Version 1.0-3 06/10/2021

 Fixed bug in deldir() (more explicitly in digOutz()) that
 was pointed out to me by Duncan Murdoch.

 Version 1.0-2 05/10/2021

 Adjusted plot.deldir() so that it no longer insists that cmpnt_lty
 be numeric, but also allows (as it should) the text strings "solid",
 "dashed", "dotted", "dotdash", \ 
"longdash", and "twodash".

 Version 1.0-1 30/09/2021

 Modified deldir() so that if argument "x" is a data frame it is
 *NOT* required to have columns named "x" and "y".  If there \ 
is no
 column named "x", the x-coordinates are taken to be the *first*
 column named neither "y" nor "z".  Likewise if there is no \ 
column
 named "y", the y-coordinates are taken to be the *first* column
 that is named neither "x" nor "z" and is not equal to the column
 previously selected to be the x-coordinates.

 Also modified deldir() so that the "x" argument is allowed to be
 a matrix.  The same convention that was used when "x" is a data
 frame is applied.

 This modification was made in response to an observation made by
 Jakob Bossek and makes use of a suggestion from Duncan Murdoch.

 Version 1.0-0 27/09/2021

 Removed/eliminated all traces of the (basically useless) facility
 for incorporating dummy points into the triangulation/tessellation.
 This facility was a historical artefact that had hung around much
 too long.

 Made an adjustment to plot.tile.list(); it no longer throws an
 error if the border argument is of length greater than 1; it now
 simply uses the first entry.

 29/09/2021

 Ran the *.Rd files through ispell and found and corrected an
 embarrassing number of errors.  Did not increment the version
 number.

 Version 0.2-13 26/09/2021

 Made some adjustments to the syntax of deldir() to accommodate
 problems encountered with finding the "z" argument.

 Changed the position of "z" in the argument list (to follow "x"
 and "y").

 Got rid of the message being issued on the first call, and the
 suppressMessage argument.

 Version 0.2-12 28/05/2021

 Adjusted the application of "\dontrun{...}" in the help files,
 eliminating its unnecessary application in some instances, and
 replacinng it by "\donttest{...}" in one instance.

 Version 0.2-11 12/05/2021

 Changed the terminology in the help and code comments so as to
 refer to the entries of the "z" argument as "tags" and not
 as "weights".  The latter term is misleading.

 Adjusted divchain() so as not to insist that the "z" argument
 be a factor.  It may now be a factor or a vector of any mode.
 If is not a factor then it is coerced into one.

 Added a "tags" component to the list returned by lawSummary().
 (This was instigated by an enquiry from Art Stock.)

 Version 0.2-10 09/02/2021

 Added the cvt() (Centroidal Voronoi Tiles) function at the
 request of Michaél Aupetit.

 Amended deldir() so that the returned object has attributes
 "round" (TRUE if argument "round" was TRUE) and \ 
"digits"
 (equal to the value of argument "digits" if "round" is TRUE,
 equal to NA otherwise.)

 Made some adjustments to the help for deldir() and plot.tile.list().

 Changed the name of Vol.Tri.Points to volTriPoints, so as to make
 it more consistent with my usual naming conventions.

 Added the "\version" macro.

 10/02/2021
 Made some adjustments to the help for cvt().

 16/02/2021
 Submitted to CRAN

 Version 0.2-9 16/01/2021

 Fixed (???) a bug in doClip() revealed by reverse-dependent package
 visualFields.  My logic (using almost.match()) was completely out
 to luntch.  Got rid of almost.match() and introduced a new function
 findNewInOld() which I *think* does things right.

 Adjusted tile.list() so that when it clipps tiles it checks for
 the availability of the polyclip package (and throws an error if
 this package is not available).

 Adjusted the help for plot.tile.list(), doing the same
 re-arrangement of plotting colours in one of the examples, as is
 used in the help for tilePerim().  The re-arrangement serves to
 produce better contrasts between contiguous tiles.
