Greetings,
 
I am attempting to build a R package, however the build fails and the
following message is ouput:
 
C:\ConstellaGroup\EPA\RAGG\package>R CMD BUILD --binary --force RAGG
* checking for file 'RAGG/DESCRIPTION' ... OK
* preparing 'RAGG':
* checking DESCRIPTION meta-information ... ERROR
Error in if (regexpr(dep_regexp, dep) == -1) { :
        missing value where TRUE/FALSE needed
Execution halted


The DESCRIPTION file is as follows:

Package: RAGG

Title: Aggregation Tool for CMAQ gridded model data

Version: 1.5

Date: 2004-08-23

Author: Nathan Shackles <nshackles@constellagroup.com>, ported from SAS code
written by Renee Jaramillo <rjaramillo@constellagroup.com>

Description: The RAGG package performs aggregation of gridded CMAQ model
data. The pacakge reads event data from Models3 IO-API files and outputs the
aggregated annual data in Models3 IO-API file(s). 

Aggegation came about as a means to provide CMAQ-based estimates of total
annual deposition and average annual concentrations. CMAQ is an episodic
model requiring detailed meteorological and emissions inputs. Because of the
extensive inputs and the time required to run CMAQ, it would be
cost-prohibitive to simulate an entire year to estimate annual quantities.
Aggregation formulas group events into clusters with similar 850-mb windflow
patters to create annual estimates.

Maintainer: Nathan Shackles <nshackles@constellagroup.com>

Depends: Models3

License: GPL version 2 or newer

Any help that can be provided is appreciated.

Thank you,

John Zajd
