This package permits to handle complex (both in the sense of complex numbers and high complexity) data as if they were ordinary arrays, except that each column MAY possess a different type. It also complete a fairly complete interface to CSV files, permitting to cope with a number of oddities, like f.i. CSV files starting with a header spread over a few lines. The resulting array tries as far as it can to mimick an array, in such a way that binary operators and usual functions will work as expected. | |||
Meta-information is also handled. Rows and columns may have a name, and this name is searchable. If for whatever reason the ordering of a CSV file changes, searching by column names will return the expected information. | |||
