Arguments

Examples

## Not run: 
# Get tibble of recent extracts
tbl_of_last_10_extracts <- get_recent_extracts_info_tbl("usa")

# Filter down to extracts with "income" in the description
description_mentions_income <- grepl(
  "[Ii]ncome",
  tbl_of_last_10_extracts$description
)
income_extracts <- tbl_of_last_10_extracts[description_mentions_income, ]

# Convert tibble of extracts to list of extracts
income_extracts <- extract_tbl_to_list(income_extracts)

# Now it's easier to operate on those elements as extract objects:
revised_income_extract <- revise_extract_micro(
  income_extracts[[1]],
  samples_to_add = "us2018a"
)

submitted_revised_income_extract <- submit_extract(revised_income_extract)
