Can R handle large datasets?
R keeps all objects in memory. One of the easiest ways to deal with Big Data in R is simply to increase the machine’s memory. Today, R can address 8 TB of RAM if it runs on 64-bit machines. That is in many situations a sufficient improvement compared to about 2 GB addressable RAM on 32-bit machines.
