problem
Good evening to everybody, I have problems to import in R a really big dataset (more than 1000000 values). Which is the best package to install? Is there someone who works with this kind of dataset and can help me, please? Thank you very much, Regards Dr.ssa Erika Frigo Department of Veterinary Sciences and Technology for Food Safety University of Milan Via Grasselli, 7 20137 Milano Tel.
