fun DataFrame.nest(colSelect: ColumnSelector = { except(*groupedBy().names.toTypedArray()) }, columnName: String = DEF_NEST_COLUMN_NAME): DataFrame
Nest repeated values in a list-variable.
There are many possible ways one could choose to nest colSelect inside a data frame. nest() creates a list of data frames containing all the nested variables: this seems to be the most useful form in practice.
Usage
nest(data, ..., columnName = "data")
colSelect
- A selection of colSelect. If not provided, all except the grouping variables are selected. You can
supply bare variable names, select all variables between x and z with x:z, exclude y with -y. For more options, see the select()
documentation.
columnName
- The name of the new column, as a string or symbol.
