When data are provided as blocks of tables within a larger data set, extract those sub-tables as a list.

When data are provided as blocks of tables within a larger data set, extract those sub-tables as a list.

Usage

find_sub_table(data, value_search, edge_search, ...)

Arguments

data

The data to extract from

value_search

The data value to search for or a function to use for the search. If a function, it should take in the data plus the ... arguments and return a two-column data frame of row and column indices to each of the values.

edge_search

A named list with either functions to search for the edge of the table or an integer indicating how far to move in that direction to find the edge. If a function, the function should take in the data, a row index (integer), a column index (integer) to start the search, a direction (one of the values in search_order), and a list indicating found_edges. The function should return a single integer of the number of cells in the given direction. The names for the list elements must be "left", "right", "up", and "down", and the order of the list elements defines the order that they will be searched.

...

Arguments passed to user-provided search functions.

Value

A list of data frames (or similar) with the found sub-tables.
