![]() This tutorial shows how to set up an account, creating public/private keys, changing the firewall, launching a machine image with the latest version of R pre-installed, connecting to the command line using Secure Shell or SSH, using R through the command line interface, and using R through a web browser ( RStudio). ![]() When I first started using R on Amazon EC2, I followed the instructions Bioconductor in the cloud (Thanks guys for maintaining an updated AMI and a great tutorial!). The downside to using cloud computing is security. For example, it is possible to rent a server with 8 cores and 68.4 GB of memory for $2 per hour instead of buying a $5,000+ server. Amazon is one provider with the Elastic Compute Cloud (EC2). In essence, cloud computing allows analysts to rent resources when they need them. It is possible to get more resources without buying a new server or more memory chips by using cloud computing. While the first solution might be the most appropriate one for repetitive tasks or production code, the second one might be quicker and easier for data scientists doing one-off analyses. Reprogramme everything in (and learn) C++.There are two ways to overcome these limitations : There are a number of limitations with an interactive programming language compared to compiled languages, such as higher memory (“Error: cannot allocate vector of size 762.9 Mb”) and processing requirements. As such, it is rapidly becoming (or has it already become?) the de facto tool for data scientists. ![]() It consists of an intuitive and interactive programming language with a vast number of extension packages (such as tnet) that allow analysts to take advantage of functions created by individuals outside the R core team. Securely using R and RStudio on Amazon’s EC2
