[R] plotting issue with timestamps

[Spencer Graves]

	  Have you considered the "zoo" package?  It has a "vignette" that I 
found very useful.  After 'install.packages("zoo")', try the following:

	  Zoo <- vignette("zoo")
	  print(Zoo)
# to open the narrative vignette in an Adobe Acrobat reader
	  edit(Zoo)
# to open a script file in RGui to make it easy for you
# to process the R commands line by line, edit them as you wish, etc.

#  If you use XEmacs, do NOT use "edit(Zoo)".  Instead do the following:

	  Stangle(Zoo$file)

# This will write the R commands to a file, which you can then open
# and process line by line as in RGui.
