ColType returns the type of column col in g.

Concat returns the concatenation of the rows in each matching group across gs.

Filter filters g to only rows where pred returns true.

FilterEq filters g to only rows where the value in col equals val.

Flatten concatenates all of the groups in g into a single Table.

Fprint prints Grouping g to w.

GroupBy sub-divides all groups such that all of the rows in each group have equal values for all of the named columns.

Head returns the first n rows in each Table of g.

HeadTables returns the first n tables in g.

Join joins g1 and g2 on tables with identical group IDs where col1 in g1 equals col2 in g2.

MapCols applies f to a set of input columns to construct a set of new output columns.

MapTables applies f to each Table in g and returns a new Grouping with the same group structure as g, but with the Tables returned by f.

NewBuilder returns a new Builder.

NewGroupingBuilder returns a new GroupingBuilder.

Pivot converts rows of g into columns.

Print(...) is shorthand for Fprint(os.Stderr, ...).

Remove returns g with column 'col' removed.

Rename returns g with column 'from' renamed to 'to'.

SortBy sorts each group of g by the named columns.

TableFromStrings converts a [][]string to a Table.

TableFromStructs converts a []T where T is a struct to a Table where the columns of the table correspond to T's exported fields.

Tail returns the last n rows in each Table of g.

TailTables returns the first n tables in g.

Ungroup concatenates adjacent Tables in g that share a group parent into a Table identified by the parent, undoing the effects of the most recent GroupBy operation.

Unpivot converts columns of g into rows.

RootGroupID is the root of the GroupID tree.

A Builder constructs a Table one column at a time.

GroupID identifies a group.

A GroupingBuilder constructs a Grouping one table a time.

A Table is an immutable, ordered two dimensional relation.

A Grouping is an immutable set of tables with identical sets of columns, each identified by a distinct GroupID.

A Slice is a Go slice value.
