Read lines from a file or string.
read_lines(file, skip = 0, n_max = -1L, locale = default_locale(), na = character(), progress = interactive()) read_lines_raw(file, skip = 0, n_max = -1L, progress = interactive())
file |
Either a path to a file, a connection, or literal data (either a single string or a raw vector). Files ending in Literal data is most useful for examples and tests. It must contain at least one new line to be recognised as data (instead of a path). |
