Description

Usage

unnest_wider(
  .df,

  names_repair = "check_unique",
  ptype = NULL,
  transform = NULL
)

Arguments

.df

A data.table or data.frame

col

Examples

df <- tidytable(
  x = 1:3,
  y = list(0, 1:3, 4:5)
)

# Automatically creates names
df %>% unnest_wider(y)

# But you can provide names_sep for increased naming control
df %>% unnest_wider(y, names_sep = "_")
