BATCH {utils} | R Documentation

## Batch Execution of R

### Description

Run R non-interactively with input from `infile` and send output (stdout/stderr) to another file.

### Usage

    R CMD BATCH [options] infile [outfile]

### Arguments

`infile` | the name of a file with R code to be executed.
`options` | a list of R command line options, e.g., for setting the amount of memory available and controlling the load/save process. If `infile` starts with a `-`, use `--` as the final option. The default options are `--restore --save --no-readline`.
`outfile` | the name of a file to which to write output. If not given, the name used is that of `infile`, with a possible ‘`.R`’ extension stripped, and ‘`.Rout`’ appended.

### Details

Use `R CMD BATCH --help` to be reminded of the usage.

By default, the input commands are printed along with the output. To suppress this behavior, add `options(echo = FALSE)` at the beginning of `infile`.

The `infile` can have end of line marked by LF or CRLF (but not just CR), and files with an incomplete last line (missing end of line (EOL) mark) are processed correctly.

### Note

Unlike `Splus BATCH`, this does not run the R process in the background. In most shells, `R CMD BATCH [options] infile [outfile] &` will do so.
