Reads a data file and returns it as dataset object.

A CSV file (see |

Further arguments to be passed to |
header |
A logical value indicating whether the file contains the names of the variables as its first line. |
sep |
The field separator character. Values on each line of the file are separated
by this character. If sep = "," (the default for |
quote |
The set of quoting characters. To disable quoting altogether, use
quote = "". See scan for the behavior on quotes embedded in quotes. Quoting is only
considered for columns read as character, which is all of them unless |

The character used in the file for decimal points. |
fill |
logical. If |
comment.char |
character: a character vector of length one containing a single character or an empty string. Use "" to turn off the interpretation of comments altogether. |
fileEncoding |
character string: if non-empty declares the encoding used on a file (not a connection) so the character data can be re-encoded. See the 'Encoding' section of the help for file, the 'R Data Import/Export Manual' and 'Note'. |
readDataset is a wrapper function that uses read.table to read the
CSV file into a data frame, transfers it from long to wide format with reshape
and puts the data to getDataset().
Returns a Dataset object.
The following generics (R generic functions) are available for this result object:
names() to obtain the field names,
print() to print the object,
summary() to display a summary of the object,
plot() to plot the object,
as.data.frame() to coerce the object to a data.frame,
as.matrix() to coerce the object to a matrix.
readDatasets() for reading multiple datasets,
writeDataset() for writing a single dataset,
writeDatasets() for writing multiple datasets.
