Sanitize degenerate table structures (Experimental)

Source: R/validate_table_struct.R
sanitize_table_struct.Rd

Experimental function to correct structure of degenerate tables by adding messaging rows to empty sub-structures.

Usage 

sanitize_table_struct(tt, empty_msg = "-- This Section Contains No Data --")

Arguments

tt

TableTree

empty_msg

character(1). The string which should be spanned across the inserted empty rows.

Value

If tt is already valid, it is returned unmodified. If tt is degenerate, a modified, non-degenerate version of the table is returned.

Details

This function locates degenerate portions of the table (including the table overall in the case of a table with no data rows) and inserts a row which spans all columns with the message empty_msg at each one, generating a table guaranteed to be non-degenerate.

Examples 


sanitize_table_struct(rtable("cool beans"))
#>                cool beans             
#> ——————————————————————————————————————
#>    -- This Section Contains No Data --

lyt <- basic_table() %>%
  split_cols_by("ARM") %>%
  split_rows_by("SEX") %>%
  summarize_row_groups()

## Degenerate because it doesn't have any analyze calls -> no data rows
badtab <- build_table(lyt, DM)
sanitize_table_struct(badtab)
#>                     A: Drug X    B: Placebo   C: Combination
#> ————————————————————————————————————————————————————————————
#> F                  70 (57.9%)    56 (52.8%)     61 (47.3%)
