[R] Remote access to R/Bioconductor on EBI's 64-bit Linux Cluster
Hi Rusers Here is a place for testing R on Cloud. http://www.ebi.ac.uk/Tools/rcloud/ http://www.ebi.ac.uk/Tools/rcloud/ Start the workbench by downloading the package for your operating system (Macintosh or Windows), or via Java Web Start, and you will get access to an instance of R running on one of EBI's powerful machines. You can install additional packages, upload your own data, work with graphics and collaborate with colleagues, all as if you are running R locally, but unlimited by your machine's memory, processor or data storage capacity. Most up-to-date R version built for multicore CPUs Access to all Bioconductor packages Access to our computing infrastructure Fast access to data stored in EBI's repositories (e.g., public microarray data in ArrayExpress) Thanks veepsirtt -- View this message in context: http://r.789695.n4.nabble.com/Remote-access-to-R-Bioconductor-on-EBI-s-64-bit-Linux-Cluster-tp4647645.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org 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.
