Questions tagged [littler]

Use this tag when asking questions about running R scripts specifically via the littler command

littler provides the R program, a simplified command-line interface for GNU R. This allows direct execution of commands, use in piping where the output of one program supplies the input of the next, as well as adding the ability for writing hash-bang scripts, i.e. creating executable files starting with, say, #!/usr/bin/r. (from http://dirk.eddelbuettel.com/code/littler.html)

littler is an alternative to the Rscript command for running R scripts from the command line.
