nest.dtplyr_stepR Documentation



This is a method for the tidyr tidyr::nest() generic. It is translated using the non-nested variables in the by argument and .SD in the j argument.


## S3 method for class 'dtplyr_step'
nest(.data, ..., .names_sep = NULL, .key = deprecated())



A data frame.


<tidy-select> Columns to nest, specified using name-variable pairs of the form new_col = c(col1, col2, col3). The right hand side can be any valid tidy select expression.


If NULL, the default, the inner names will come from the former outer names. If a string, the new inner names will use the outer names with names_sep automatically stripped. This makes names_sep roughly symmetric between nesting and unnesting.


Not supported.


A lazy_dt().


if (require("tidyr", quietly = TRUE)) {
  dt <- lazy_dt(tibble(x = c(1, 2, 1), y = c("a", "a", "b")))
  dt %>% nest(data = y)

  dt %>% dplyr::group_by(x) %>% nest()
