Provides access to a copy of the command line arguments supplied when this R session was invoked.
commandArgs(trailingOnly = FALSE)
trailingOnly |
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.
