Extract Command Line Arguments
Provides access to a copy of the command line arguments supplied when this R session was invoked.
commandArgs(trailingOnly = FALSE)
- logical. Should only arguments after --args be returned?
These arguments are captured before the standard R command line processing takes place. This means that they are the unmodified values. This is especially useful with the --args command-line flag to R, as all of the command line after that flag is skipped.
A character vector containing the name of the executable and the
user-supplied command line arguments. The first element is the name
of the executable by which R was invoked. The exact form of this
element is platform dependent: it may be the fully qualified name, or
simply the last component (or basename) of the application, or for an
embedded R it can be anything the programmer supplied.If
trailingOnly = TRUE, a character vector of those arguments (if any) supplied after --args.
commandArgs() ## Spawn a copy of this application as it was invoked, ## subject to shell quoting issues ## system(paste(commandArgs(), collapse = " "))
