Type extension	Description
`Virtual.ReadCsv(path, ?searchColumns, ?columnKeys, ?byteOffsetIndex, ?hasHeaders)` Full Usage: `Virtual.ReadCsv(path, ?searchColumns, ?columnKeys, ?byteOffsetIndex, ?hasHeaders)` Parameters: path : `string` ?searchColumns : `VirtualSearchColumn list` ?columnKeys : `string list` ?byteOffsetIndex : `bool` ?hasHeaders : `bool` Returns: `Frame<int64, string>`	Load a CSV file as a virtual frame with ordinal row index `0 .. N-1`. Extended Type: `Virtual` path : `string` ?searchColumns : `VirtualSearchColumn list` ?columnKeys : `string list` ?byteOffsetIndex : `bool` ?hasHeaders : `bool` Returns: `Frame<int64, string>`
`Virtual.ReadCsv(path, indexColumn, ?searchColumns, ?columnKeys, ?byteOffsetIndex, ?hasHeaders)` Full Usage: `Virtual.ReadCsv(path, indexColumn, ?searchColumns, ?columnKeys, ?byteOffsetIndex, ?hasHeaders)` Parameters: path : `string` indexColumn : `string` ?searchColumns : `VirtualSearchColumn list` ?columnKeys : `string list` ?byteOffsetIndex : `bool` ?hasHeaders : `bool` Returns: `Frame<'R, string>` Type parameters: 'R (requires equality)	Load a CSV file as a virtual frame. When `indexColumn` is set, that column becomes the row index only if it is strictly increasing and unique in file order; otherwise an ordinal index is used (trace warning). Specify the row key type explicitly (for example `DateTimeOffset` for a timestamp column). Extended Type: `Virtual` path : `string` indexColumn : `string` ?searchColumns : `VirtualSearchColumn list` ?columnKeys : `string list` ?byteOffsetIndex : `bool` ?hasHeaders : `bool` Returns: `Frame<'R, string>`
`Virtual.ReadCsvDirectory(directory, ?searchPattern, ?searchColumns, ?columnKeys, ?byteOffsetIndex, ?hasHeaders)` Full Usage: `Virtual.ReadCsvDirectory(directory, ?searchPattern, ?searchColumns, ?columnKeys, ?byteOffsetIndex, ?hasHeaders)` Parameters: directory : `string` ?searchPattern : `string` ?searchColumns : `VirtualSearchColumn list` ?columnKeys : `string list` ?byteOffsetIndex : `bool` ?hasHeaders : `bool` Returns: `Frame<int64, string>`	Load matching CSV files in a directory as one ordinal virtual frame (files sorted by name). Rows are addressed 0 .. N-1 across files; all files must share the first file's header. Extended Type: `Virtual` directory : `string` ?searchPattern : `string` ?searchColumns : `VirtualSearchColumn list` ?columnKeys : `string list` ?byteOffsetIndex : `bool` ?hasHeaders : `bool` Returns: `Frame<int64, string>`
