Dear Felix,

Thanks. That was most useful. I am having trouble though exporting 
values of variables to the R environment from within the playwith.

Say I need to do a claculation by setting up an extra  button within

playwith(xyplot(dat[,c(1,i)]),  parameters = list(i = 1:100,
    do_something = function(playState) print(playState$env$i),
    do_something_else = function(playstate) ###Export here mean value of sequence playState$env$i###
)
)

Can I pass the value of this to the rest of R ? I could not find 
something in the help pages. Can you direct me to it please?

Thanks +

Best regards,
Costas
