Layout Creating Function to Add Row Total Counts

Source: R/utils_rtables.R
add_rowcounts.Rd

[Stable]

This works analogously to rtables::add_colcounts() but on the rows. This function is a wrapper for rtables::summarize_row_groups().

Usage 

add_rowcounts(lyt, alt_counts = FALSE)

Arguments

lyt

(layout)
input layout where analyses will be added to.

alt_counts

(flag)
whether row counts should be taken from alt_counts_df (TRUE) or from df (FALSE). Defaults to FALSE.

Value

A modified layout where the latest row split labels now have the row-wise total counts (i.e. without column-based subsetting) attached in parentheses.

Note

Row count values are contained in these row count rows but are not displayed so that they are not considered zero rows by default when pruning.

Examples 

basic_table() %>%
  split_cols_by("ARM") %>%
  add_colcounts() %>%
  split_rows_by("RACE", split_fun = drop_split_levels) %>%
  add_rowcounts() %>%
  analyze("AGE", afun = list_wrap_x(summary), format = "xx.xx") %>%
  build_table(DM)
