Description Usage Arguments Value Author(s) See Also Examples

Reads one or several QuantArray files into one QuantArrayData object. Currently QuantArray v2 and v3 are supported. If the version is not recognized it will try to make a best guess and read it in anyway. However, it can not be guaranteed that all fields will be of the correct data type.

This method also reads Unicoded QuantArray files. If the file is Unicoded it is first translated into a temporary ASCII file, which is then read. The translation from Unicode to ASCII is done by "brute force", i.e. by excluding the hi-bytes and only keeping the lo-bytes. This means that some characters will be incorrectly translated. If that happens, a warning will be given, otherwise not.

1	QuantArrayData$read(filename=NULL, path=NULL, pattern=NULL, verbose=FALSE, ...)

`filename`	A `vector` of filenames. Either `pattern` or `filename` must be specified.
`path`	A string (or an optional `vector` of paths if `filename` is specified) to the files.
`pattern`	A pattern string for matching filenames. Either `pattern` or `filename` must be specified.
`verbose`	If `TRUE`, information will printed out during the reading of the file.

Returns a QuantArrayData object.
