def coo(file: String, arrayIndexOrigin: Int = 0): SparseDataset

Reads spare dataset in coordinate triple tuple list format.
Reads spare dataset in coordinate triple tuple list format. Coordinate file stores a list of (row, column, value) tuples:
```
instanceID attributeID value
instanceID attributeID value
instanceID attributeID value
instanceID attributeID value
...
instanceID attributeID value
instanceID attributeID value
instanceID attributeID value
```
Ideally, the entries are sorted (by row index, then column index) to improve random access times. This format is good for incremental matrix construction.
Optionally, there may be 2 header lines
```
D    // The number of instances
W    // The number of attributes
```
or 3 header lines
```
D    // The number of instances
W    // The number of attributes
N    // The total number of nonzero items in the dataset.
```
These header lines will be ignored.
file
the file path.
arrayIndexOrigin
the starting index of array. By default, it is 0 as in C/C++ and Java. But it could be 1 to parse data produced by other programming language such as Fortran.
def csv(file: String, response: Option[(Attribute, Int)] = None, comment: String = "%", missing: String = "?", header: Boolean = false, rowNames: Boolean = false): AttributeDataset

def sb(file: String): BinarySparseDataset

def table(file: String, response: Option[(Attribute, Int)] = None, delimiter: String = "\\s+", comment: String = "%", missing: String = "?", header: Boolean = false, rowNames: Boolean = false): AttributeDataset

Reads a delimited text file with response variable.
Reads a delimited text file with response variable. By default, the parser expects a white-space-separated-values file. Each line in the file corresponds to a row in the table. Within a line, fields are separated by white spaces, each field belonging to one table column. This class can also be used to read other text tabular files by setting delimiter character such ash ','. The file may contain comment lines (starting with '%') and missing values (indicated by placeholder '?').
file
the file path
response
optional response variable attribute and the column index of response variable. The column index starts at 0.
delimiter
delimiter string
comment
the start of comment lines
missing
the missing value placeholder
header
true if the first row is header/column names
rowNames
true if the first column is row id/names
returns
an attribute dataset

def txt(file: String): AttributeDataset

Reads TXT microarray gene expression file.
Reads TXT microarray gene expression file. The TXT format is a tab delimited file format that describes an expression dataset. It is organized as follows:
The first line contains the labels Name and Description followed by the identifiers for each sample in the dataset. The Description is optional.
Line format:
```
Name(tab)Description(tab)(sample 1 name)(tab)(sample 2 name) (tab) ... (sample N name)
```
Example:
```
Name Description DLBC1_1 DLBC2_1 ... DLBC58_0
```
The remainder of the file contains data for each of the genes. There is one line for each gene. Each line contains the gene name, gene description, and a value for each sample in the dataset. If the first line contains the Description label, include a description for each gene. If the first line does not contain the Description label, do not include descriptions for any gene. Gene names and descriptions can contain spaces since fields are separated by tabs.
Line format:
```
(gene name) (tab) (gene description) (tab) (col 1 data) (tab) (col 2 data) (tab) ... (col N data)
```
Example:
```
AFFX-BioB-5_at AFFX-BioB-5_at (endogenous control) -104 -152 -158 ... -44
```

def wavefront(file: String): (Array[Array[Double]], Array[Array[Int]])

Reads a Wavefront OBJ file.
Reads a Wavefront OBJ file. The OBJ file format is a simple format of 3D geometry including the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices. Vertices are stored in a counter-clockwise order by default, making explicit declaration of face normals unnecessary. OBJ coordinates have no units, but OBJ files can contain scale information in a human readable comment line.
Note that we parse only vertex and face elements. All other information ignored.
file
the file path
returns
a tuple of vertex array and edge array.
def xstream(file: String): AnyRef

Reads an object/model that was serialized by XStream.
