Since the databases that I handle with are very large, I need answers to some questions:
1) Can I work with R data frames like databases in SAS, that is, with data frames storage in files instead of memory allocation? 2) Can I use SQL codes to work with R data frames? Note that I ask for the direct use, with no need to use a "channel" or to export data frames to a DBMS. Thanks. ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
