It also provides a fairly complete interface to CSV files, permitting to cope with a number of oddities, like e.g., CSV files starting with a header spread over a few lines. The resulting array tries as far as it can to mimic 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. | Meta-information is also handled.
