Brace and Wildcard expansion on file paths

glob() is a wrapper around Sys.glob() that uses expand_braces() to support both brace and wildcard expansion on file paths.

glob(paths, ..., engine = getOption("bracer.engine", NULL))

Arguments

paths: character vector of patterns for relative or absolute filepaths.
...: Passed to Sys.glob()
engine: If 'r' use a pure R parser. If 'v8' use the 'braces' Javascript parser via the suggested V8 package. If NULL use 'v8' if 'V8' package detected else use 'r'; in either case send a message() about the choice unless getOption(bracer.engine.inform') is FALSE.

  dir <- system.file("R", package="bracer")
  path <- file.path(dir, "*.{R,r,S,s}")
  glob(path, engine = "r")
#> character(0)
