Run R non-interactively with input from
send output (stdout/stderr) to another file.
the name of a file with R code to be executed.
a list of R command line options, e.g., for setting the
amount of memory available and controlling the load/save process.
the name of a file to which to write output. If not
given, the name used is that of
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
infile, or use option --slave.
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.
A final expression proc.time() will be executed after the input
script unless the latter calls
q(runLast = FALSE) or is aborted.
This can be suppressed by the option --no-timing.
Additional options can be set by the environment variable
R_BATCH_OPTIONS: these come after the default options (see the
description of the
options argument) and before any options
given on the command line.
Splus BATCH on a Unix-alike, this does not run the R
process in the background.
In most shells,
will do so.
