I am having trouble using get.bnddata() in the RArcInfo package.  I
installed the version 0.2 binary of the package for Windows and am using R
1.4.1 on Windows NT 4.0.  I have had no problems importing and plotting arc
data with get.arcdata() and plotarc().  plotpal() also works fine.  I've
been able to use get.arcdata(), get.labdata(), get.paldata(),
get.tablenames(), get.tablefields(), get.tabledata().  When I try
get.bnddata() as follows, I get an error:
	> wet.bnd <- get.bnddata("wetlands\\info", "WETLANDS.BND")
	Error in get.bnddata("wetlands\\info", "WETLANDS.BND") : Couldn't
open table

get.tablenames() shows that the table exists
	                         TableName InfoFile NFields RecSize NRecords
	1 WETLANDS.BND                      ARC0000       1      16        1
	2 WETLANDS.PAT                      ARC0001       1      26      355

and if I use get.tabledata() the table will open (but the values are set to
	> wet.bnd <- get.tabledata("wetlands\\info", "WETLANDS.BND")
	> wet.bnd
	$"XMIN            "
	[1] 0

	$"YMIN            "
	[1] 0
	$"XMAX            "
	[1] 0
	$"YMAX            "
	[1] 0

I'm probably overlooking something simple.  What might it be?

Also, is it possible to change the extent of the view; perhaps by changing
the boundary values?

Thanks in advance.
