[Rsiena-help] Two RSiena points

[Christian Steglich]

Hello Ruth & Tom,

teaching creates a certain pressure to do things ... I've been teaching 
two days of network evolution modeling with RSiena here in Lexington, 
Ky, so I had to abandon the old Siena 3 platform, at least for a while, 
but it is addictive. As Josh may already have written you, we 
encountered two mistakes that you should know of:

    * there is a letter '0' missing in line 170 of the R Script that is
      on Tom's website, together with the s50 data. The script reads "aa
      <- matrix(nrow=5, ncol=2)" while the number of rows must be 50.

    * the siena01Gui() call is futile because currently you cannot
      specify any models. If you want to, instead of opening the
      fix(effects) screen, you get the error message "Error in
      `[.data.frame`(name, , priorityColumns) : undefined columns
      selected". Josh suspected that this may have something to do with
      the new time heterogeneity test.

As I will be teaching another course in ~10 days, I would appreciate it 
very much if these points could be repaired. For the script, I obviously 
can do that myself... but not for the Gui. We will work with scripts in 
the first place, but nonetheless I want people to see how (and THAT) the 
Gui works as well. At some moment in the coming days, I need to send the 
zipped R packages we will work with to the student assistant managing 
the final software distribution (I think they use CDs)...

By the way, Maarten - if you read this - we had no problems with 
'sienaModelCreate' during the workshop. What you report sounds weird...

Thanks & Greetings,
Christian
