I'm currently investigating QuantConnect for use as a production platform. I have a research stack developed in R and want to know if any interfacing capability exists when using LEAN via the QuantConnect servers. (I know in "open-source" mode I can use R.NET - but then as I understand it I won't be able to access QuantConnect's tick data.)

In similar vein, what is the policy on generating data artifacts and/or data export? I have a two stage process where I generate a number of factors; these factors need to be stored somewhere and referenced in order to do actual trading. Is there space on the online servers that I can dump the factors, or if not, can I connect to an external SQL server to dump/pull these factors from within the online servers?
