Character vector of strings to interpret as missing values. Set this
option to character() to indicate no missing values.
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.
trim_ws
Should leading and trailing whitespace (ASCII spaces and tabs) be trimmed from
each field before parsing it?
