Talk:R

Changes wanted[edit]

Refer to Utiliser des modules instead of lengthy modules explanation
R on login node should only be for (1) small tests and (2) package installation
sbatch for non-interactive work, salloc for interactive, refer to Running jobs
install.packages() will fail from Graham compute nodes
Recommend CRAN mirrors? http://cran.utstat.utoronto.ca/, http://cran.stat.sfu.ca/, http://cloud.r-project.org/ ?
- Is https: preferred to http: in this context?
- Could we open paths to these from Graham compute?
In "Exploiting parallelism":
- Acknowledge variety of solutions at https://cran.r-project.org/web/views/HighPerformanceComputing.html
- Don't assume reader has prior understanding of MPI, threading, "multicore", etc etc
- Mention library(parallel)
- Acknowledge terminology clash: "Following snow, a pool of worker processes listening via sockets for commands from the master is called a 'cluster' of nodes."
