If not is.na(sep), then sep must be a character vector
of length one. In that case, sep is interpreted as a
type separator in the input file. This separator the serves as an
additional type separator, next to the end of each line.
The end of a line always indicated a separator between types (in other
words, types cannot cross lines).
file_encoding
The file encoding used in the input file.
trim_types
Logical. Should leading and trailing
white space should be stripped from the types.
remove_duplicates
Logical. Should duplicates be removed from x
prior to coercing to a vector of types.
sort
Logical. Should x be
alphabetically sorted prior to coercing to a vector of types;
this argument is ignored if remove_duplicates is TRUE,
because the result of removing duplicates is always sorted.
