Thank you all so much for your helpful assistance! Having worked with
Ucinet for several years, I feel that I already got the basics of R
although I've only played around with it for a day so far!

Regarding my specific problem, I got it solved now, thanks to Anthon and
Katrien. For the archives, in case other might have similar problems in
the future, this is how I got this to work:

Beginning with a tab-separated text file containing my network data
(though without any row/col headers), I load this into R using the
following command:

x<-as.matrix(read.csv('cont.txt',header=FALSE,sep='\t'))

Then, using Zibernas blockmodeling package, I calculate (traditional)
REGE eq.factors using:

e<-REGE.for(M=x,iter=3,E=1)

I then write the results in 'e' into a tab-separated file using:

write.table(e,file='results.txt',sep='\t')

Easy peasy! (Except that 'e' contains loads more info than just the
final equivalence matrix...)

Thx very much again!

Yours,
Carl
