R help - Aug 2005 - Converting a list from R to Stata

Dear all,
I have a list containing 150 simulated datasets in R. Is there a way to 
convert it to the Stata format such that I will be able to apply some Stata 
functions on each dataset in the list?
Thank you in advance,
Vicky Landsman.

For Stata your best best is probably to stack all 150 datasets into one 
long data frame and add an id variable, so you can then -by id:- your 
analysis.
   big.data.frame <- do.call("rbind", the.list.of.datasets)
will stack them for you and
   big.data.frame$id <- rep(1:150, sapply(the.list.of.data.sets, nrow))
will make the id variable.
