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.
