Version 0.4-2
-------------

* Some additional variables in the `citycensus' table.


Version 0.4-1
-------------

* Changed citation to R News article.

* collapseEndpoints() now removes the `agecat' variable from the
resulting dataframe.  Also, much more error checking is done --- only
the endpoints that are present in the dataframe will be collapsed.  A
`mortality' argument was added to collapseEndpoints() for specifying
which endpoints to collapse.


Version 0.4
-----------

* There is a mailing list available for announcements.  See
http://www.ihapss.jhsph.edu/data/NMMAPS/R/ for details.

* Added some simple regression tests in the tests/ directory.

* The citation information was previously incorrect in number of ways
and has been fixed.

* `listDBCities(full.names = TRUE)' and `listAllCities(full.names = TRUE)'
both list the "unique" city name from the `cities' table.

* Added a CITATION file.  The current reference for `NMMAPSdata' can be
found by typing `citation("NMMAPSdata")' at the command prompt.  
NMMAPScite() simply calls citation() now.

* A table of census data for the cities is now included in the dataframe
`citycensus'.  The `citycensus' dataframe can be loaded using `data()' and
short variable descriptions can be retrieved using getVarDesc().

* `NMMAPSdata' now requires R >= 2.0.0 and is lazy loaded.


Version 0.3-4
-------------

* There is a new vignette in the inst/doc directory giving a brief
description of how the pollutant data were processed from the raw
monitor data.  The vignette can be viewed by typing
`vignette("PollutantProcess")' at the command prompt.

* cityApply() has two new arguments: `hookFun' can be a function or a
list of functions that will be applied to the output of `FUN' from
each city; `wrapInTry', if `TRUE', wraps the call to `FUN' with a call
to try().  The default is `FALSE'.

* New function getVarDesc() retrieves short descriptions of the
variables in a dataframe from the `variables' table (if those
descriptions are available).

* Added new documentation page which contains the names of all the
variables in the full/raw dataframes and a short description of each. See
`?variableDesc'.  This information is taken from the `variables' table.


Version 0.3-3
-------------

* The argument `verbose' was added to cityApply() which, when `TRUE',
prints the names of the cities as they are passed to `FUN'.

* A new preprocessing function reduced() was added to the example
processing functions.  This function simply returns a dataframe with a
reduced set of variables.  This reduced set is currently what is
available from IHAPSS if you download the individual compressed
ASCII/CSV files.

* A vignette is now included with the package which can be viewed by
typing `vignette("NMMAPSdata")' at the command prompt.

* attachCity() now has a `pos' argument which defaults to 2.
