Thanks to Kit Baum, various packages 
have been updated on SSC. Details 
follow my signature. If you installed 
any of these before, please update by 

. ssc inst <package>, replace 

To find out whether you have installed
<package>, so long as you installed it 
using -ssc- or -net-, go 

. ado dir <package> 

For example, to see whether you installed
any of the packages 

catplot tabstatmat tsspell 

you can go 

. foreach p in catplot tabstatmat tsspell { 
. 	ado dir `p' 
. } 


catplot (Stata 8 required) 

Eva Poen suggested an immediate version of 
-catplot-. That is, just as you can use -tabi- 
to get results from a two-way table, without
the data being entered into Stata, so also 
you could get a -catplot-. 

A very rough version was posted
on Statalist as -catploti-. This is a better 
version of -catploti-. -catplot- is unaffected. 

tabstatmat (Stata 8 required) 

Fix to help file. 

tsspell (Stata 7 required) 

Extra material in help file. How to tackle 
the following problem is now documented, 
with code example. The program is unchanged. 

A liberal definition of a spell might allow 
inclusion of periods that were no longer than 
some specified number of observations, even though
they do not fit the strict definition of that spell. 
For example, two spells of heavy rain separated by 
a brief period might be regarded, meteorologically, 
as part of the same spell. More generally, we might
consider including any part of the data that is not 
part of a strictly identified spell, i.e. before the 
first spell, between two spells, or after the last 
spell. One approach to this is a two-pass process. In the
second pass, periods omitted from spells on the first 
pass are themselves treated as another kind of spell. 
Then once the length of each gap has been calculated, 
the new definition is just the old definition or the
fact that gap lengths are acceptable.
