R: Redirect Input

source {base}

R Documentation

Redirect Input

Description

source causes R to accept its input from the named file (the name must be quoted). Input is read from that file until the end of the file is reached. parse is used to scan the files in, they are then evaluated sequentially in the chosen environment.

Usage

source(file, local = FALSE, echo = debug, print.eval = echo,
       debug = FALSE, max.deparse.length = 150)

Arguments

`file`	the name of the file to read from (quoted).
`local`	if `local` is `FALSE`, the statements scanned are evaluated in the global environment, otherwise in the local calling source.
`echo`	logical; if `TRUE`, each expression is printed after parsing, before evaluation.
`print.eval`	logical; if `TRUE`, the result of `eval(i)` is printed for each expression `i`; defaults to `echo`.
`debug`	if `TRUE`, more diagnostics are printed during parsing and evaluation of input, including extra info for each expression.
`max.deparse.length`	integer; is used only if `echo` is `TRUE` and gives the maximal length of the “echo” of a single expression.
