Either a path to a file, a connection, or literal data
(either a single string or a raw vector).
Files ending in .gz, .bz2, .xz, or .zip will
be automatically uncompressed. Files starting with http://,
https://, ftp://, or ftps:// will be automatically
downloaded. Remote gz files can also be automatically downloaded &
decompressed.
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).
skip
Number of lines to skip before reading data.
n_max
Number of lines to read. If n is -1, all lines in
file will be read.
locale
The locale controls defaults that vary from place to place.
The default locale is US-centric (like R), but you can use
locale to create your own locale that controls things like
the default time zone, encoding, decimal mark, big mark, and day/month
names.
progress
Display a progress bar? By default it will only display
in an interactive session. The display is updated every 50,000 values
and will only display if estimated reading time is 5 seconds or more.
Value
A character vector with one element for each line.
