Details

Called on a dm object, these methods create a copy of all tables in the dm. Depending on the size of your data this may take a long time.

Examples

# NOT RUN {
financial <- dm_financial_sqlite()

financial %>%
  pull_tbl(districts) %>%
  dbplyr::remote_name()

# compute() copies the data to new tables:
financial %>%
  compute() %>%
  pull_tbl(districts) %>%
  dbplyr::remote_name()

# collect() returns a local dm:
financial %>%
  collect() %>%
  pull_tbl(districts) %>%
  class()
# }
