Questions tagged [r]

R is a programming language and software environment for statistical computing and graphics.  Use this tag, together with other appropriate ones, for questions that are incidentally or indirectly related to the R language — for example, how to format data for use in R programs, how to display output, or how to resolve failures when installing or running R.

Questions about programming and software design and development are off-topic at Super User; they should be asked at Stack Overflow.  Similarly, questions about the design of experiments, statistical analysis techniques and advanced data visualization are off-topic here; consider asking them at our Cross Validated site.  See:
