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.
