[Rsiena-help] More flexibility on using Clusters

[Ruth Ripley]

Dear George,

I am not working on RSiena any more, but wrote the R function siena07.

It seems from the help for makePSOCKCluster in the parallel package that
you can set up the port via an environment variable R_PARALLEL_PORT.
Have you tried this?

If this does not help, RSiena is on R-forge
(https://r-forge.r-project.org/R/?group_id=461), and you could ask to
join the team of developers.

It is also possible to change the source code within a package using the
functions insertSource() or fixInNamespace().

Hope this helps,

Ruth
