Parse Expressions

parse returns the parsed but unevaluated expressions in a list. Each element of the list is of mode expression.

parse(file = "", n = NULL, text = NULL, prompt = NULL, white = FALSE)

`file`	the name of a file to read the expressions from. If the `file` is `""` and `text` is missing or `NULL` then input is taken from the keyboard.
`n`	the number of statements to parse. If `n` is negative the file is parsed in its entirety. When parsing takes place from the keyboard, `n` is always 1.
`text`	text to parse, quoted.
`prompt`	the prompt to print when parsing from the keyboard
`white`	if `TRUE` then any white space separates expressions otherwise only newlines or semicolons do.

# parse 3 statements from the file "xyz.Rdmped"
parse(file = "xyz.Rdmped", n = 3)
