Types ¶
type Dataframe ¶
type Dataframe struct {
Header map[string]int
Index map[string]int
Rows [][]string
// contains filtered or unexported fields
}
Dataframe stores data as a two-dimensional string slice with header and index as maps or named indeces.
func FromFile ¶
FromFile creates a dataframe and loads in data from the given input file. The first row is assumed to be the header.
func FromSlice ¶
FromSlice creates a new dataframe and loads data from the given slice. The first row is assumed to be the header.
func NewDataFrame ¶
NewDataFrame returns an empty dataframe struct.
func (*Dataframe) AddColumn ¶
AddColumn adds a new column with the given name to the end of the dataframe and stores the given null value in each row.
func (*Dataframe) AddRow ¶
AddRow adds a string slice to dataframe and stores the index value in Index if using.
func (*Dataframe) Clone ¶
Clone returns a copy of the dataframe's structure. Specifically, it returns an empty dataframe with the same header and index column name.
func (*Dataframe) Compare ¶
Compare returns an error if target dataframe is not equal to d (for testing).
func (*Dataframe) DeleteColumn ¶
DeleteColumn removes the given column from dataframe.
func (*Dataframe) Dimensions ¶
Dimensions returns row and column lengths (respectively).
func (*Dataframe) Extend ¶
Extend appends rows from n to the current dataframe. Rows with redundant index values will be skipped.
func (*Dataframe) FormatHeader ¶
FormatHeader formats header for writing. Prepends index name if needed.
func (*Dataframe) GetCellFloat ¶
GetCellFloat returns the value of the given cell as float64. Returns an error if it cannot be converted.
func (*Dataframe) GetCellInt ¶
GetCellInt returns the value of the given cell as int. Returns an error if it cannot be converted.
func (*Dataframe) GetColumnUnique ¶
GetColumnUnique returns all unique values from the given column.
func (*Dataframe) RenameColumn ¶
RenameColumn changes the name of column o to n. Returns an error if o is not found.
func (*Dataframe) RenameRow ¶
RenameRow changes the name of row o to n. Returns an error if o is not found.
func (*Dataframe) SliceRow ¶
SliceRow returns a slice of the given row between start and end (not including the value at end).
func (*Dataframe) ToSlice ¶
ToSlice returns dataframe as a two-dimensional string slice (inserts index values if needed but does not include header).
func (*Dataframe) UpdateCell ¶
UpdateCell replaces the value in a given cell with v.
type Series ¶
type Series struct {
// Encapsulates error so it can be returned through channel
Error error
// Same as dataframe header
Header map[string]int
// Interger index of row in Rows slice
Index int
// Name of row if index map is set
Name string
// Copy of row from dataframe at index
Row []string
// contains filtered or unexported fields
}
func (*Series) GetCellFloat ¶
GetCellFloat returns the value of the given cell as float64. Returns an error if it cannot be converted.
func (*Series) GetCellInt ¶
GetCellInt returns the value of the given cell as int. Returns an error if it cannot be converted.
func (*Series) UpdateCell ¶
UpdateCell updates col to val. Returns error if column name is not in header.
