unnest.tbl_kusto_abstract: Unnest method for Kusto tables

In AzureKusto: Interface to 'Kusto'/'Azure Data Explorer'

Unnest method for Kusto tables

Description

This method takes a list column and expands it so that each element of the list gets its own row. unnest() translates to Kusto's mv-expand operator.

Usage

## S3 method for class 'tbl_kusto_abstract'
unnest(
  data,
  cols,
  ...,
  keep_empty = FALSE,
  ptype = NULL,
  names_sep = NULL,
  names_repair = NULL,
  .drop = NULL,
  .id = NULL,
  .sep = NULL,
  .preserve = NULL
)

Arguments

data	A Kusto tbl.
cols	Specification of columns to unnest.
...	: previously you could write df %>% unnest(x, y, z). Convert to df %>% unnest(c(x, y, z)). If you previously created a new variable in unnest() you'll now need to do it explicitly with mutate(). Convert df %>% unnest(y = fun(x, y, z)) to df %>% mutate(y = fun(x, y, z)) %>% unnest(y).
keep_empty	Needed for agreement with generic. Not otherwise used. Kusto does not keep empty rows.
ptype	Needed for agreement with generic. Not otherwise used.
names_sep	Needed for agreement with generic. Not otherwise used.
names_repair	Needed for agreement with generic. Not otherwise used.
.drop	Needed for agreement with generic. Not otherwise used.
.id	Data frame identifier - if supplied, will create a new column with name .id, giving a unique identifier. This is most useful if the list column is named.
.sep	Needed for agreement with generic. Not otherwise used.
.preserve	Needed for agreement with generic. Not otherwise used.
