Delegates to read.delim where the separator is inferred from the file extension (CSV or TXT).
For CSV files the delimiter is set to "," while for TXT file "\t" is used. Also sets
some default argument values as used by Core Hunter.

)Data frame.
File path.
the set of quoting characters. To disable quoting
altogether, use quote = "". See scan for the
behaviour on quotes embedded in quotes. Quoting is only considered
for columns read as character, which is all of them unless
colClasses is specified.
a vector of row names. This can be a vector giving the actual row names, or a single number giving the column of the table which contains the row names, or character string giving the name of the table column containing the row names.
If there is a header and the first row contains one fewer field than
the number of columns, the first column in the input is used for the
row names. Otherwise if row.names is missing, the rows are
numbered.
Using row.names = NULL forces row numbering. Missing or
NULL row.names generate row names that are considered
to be ‘automatic’ (and not preserved by as.matrix).
a character vector of strings which are to be
interpreted as NA values. Blank fields are also
considered to be missing values in logical, integer, numeric and
complex fields. Note that the test happens after
white space is stripped from the input, so na.strings
values may need their own white space stripped in advance.
logical. If TRUE then the names of the
variables in the data frame are checked to ensure that they are
syntactically valid variable names. If necessary they are adjusted
(by make.names) so that they are, and also to ensure
that there are no duplicates.
logical. Used only when sep has
been specified, and allows the stripping of leading and trailing
white space from unquoted character fields (numeric fields
are always stripped). See scan for further details
(including the exact meaning of ‘white space’),
remembering that the columns may include the row names.
logical: should character vectors be converted
to factors? Note that this is overridden by as.is and
colClasses, both of which allow finer control.
