Types

type Columns

type Columns []string

type Table

type Table struct {
	Name    string
	Columns table.Columns
	Rows    [][]float64
}

Table is useful for working on CSV data. It stores records as `[]string` with typed formatting information per-column to facilitate transformations.

func FromTableString

func FromTableString(tbl *table.Table, skipEmptyRows bool, colIndexes []uint) (*Table, error)

func NewTable

func NewTable(name string) *Table

NewTable returns a new empty `Table` struct with slices and maps set to empty (non-nil) values.

func ReadFile

func ReadFile(filename string, skipEmptyRows bool) (*Table, error)

func (*Table) PointXYsColumnIndexes

func (tbl *Table) PointXYsColumnIndexes(xColIdx, yColIdx int) (point.PointXYs, error)

func (*Table) PointXYsColumnNames

func (tbl *Table) PointXYsColumnNames(xColName, yColName string) (point.PointXYs, error)

func (*Table) ValuesColumnIndex

func (tbl *Table) ValuesColumnIndex(colIndex uint) ([]float64, error)

func (*Table) ValuesColumnName

func (tbl *Table) ValuesColumnName(colName string) ([]float64, error)
