Yes of course. 'Insert Command Template' goes hand in hand with  
'Command Usage'.

My point was that 'Command Usage' could be sometimes helpful, if I  
only want to know, what is the default of a variable, for instance.
I don't know who wrote this command and why did he/she use 'texscan'  
to parse the R help files written in TeX.
I also don't know this function 'texscan' but I suppose that this  
function gives you the text specified within the LaTeX tag \begin 
{Usage}.

In order to use 'Command Usage' for everyone I rewrote it by  
searching within the HTML help files without any 'foreign' functions  
and I changed the behaviour of the system function 'find' to suppress  
the error messages.

No, in that case you can easily write COM=`cat`.

My other question was who is 'responsible' for the R bundle and can  
upload this changed version?
I know the bundles are more or less a collaborative work but I  
believe that someone should organize these ;)

Best,
