![]() ![]() This is similar to grouping by the id_cols then summarizing the Id_cols must be supplied for unused_fn to be useful, since otherwiseĪll unspecified columns will be considered id_cols. The default drops all unused columns from the result. Optionally, a function applied to summarize the values from This can be a named list if you want to apply different aggregations Id_cols and names_from columns does not uniquely identify an You will typically use this when the combination of Optionally, a function applied to the value in each cell This can be a named list if you want to apply different fill values to Value should be filled in with when missing. Optionally, a (scalar) value that specifies what each Use "minimal" to allow duplicates in the output, or "unique" toĭe-duplicated by adding numeric suffixes. The default, "check_unique" is to error if the columns are duplicated. What happens if the output has invalid column names? Names will be sorted, identical to what names_sort would produce. ![]() Represented in the data will become explicit. Will contain column names corresponding to a complete expansion of all Should the values in the names_from columns be expandedīy expand() before pivoting? This results in more columns, the output Naming scheme of the form: value1_name1, value2_name1, value1_name2, value2_name2. "slowest" varies names_from values slowest, resulting in a column Naming scheme of the form: value1_name1, value1_name2, value2_name1, value2_name2. "fastest" varies names_from values fastest, resulting in a column In what order should the resulting column names be combined? Multiple unique values, and multiple values_from columns are provided, When names_from identifies a column (or columns) with Should the column names be sorted? If FALSE, the default,Ĭolumn names are ordered by first appearance. Instead of names_sep and names_prefix, you can supplyĪ glue specification that uses the names_from columns (and special Variables, this will be used to join their values together into a single If names_from or values_from contains multiple Particularly useful if names_from is a numeric vector and you want toĬreate syntactic variable names.
