## Creating an Example Table

In order to generate an ARD (Analysis Results Dataset), we first need to create a table from which all the necessary information will be retrieved. We will borrow a simple table from this vignette about clinical trials.

    library(rtables)
    ADSL <- ex_adsl # Example ADSL dataset

    # Very simple table
    lyt <- basic_table() %>%
      split_cols_by("ARM") %>%
      analyze(c("AGE", "SEX"))

    tbl <- build_table(lyt, ADSL)
    tbl
    #                      A: Drug X   B: Placebo   C: Combination
    # ————————————————————————————————————————————————————————————
    # AGE
    #   Mean                 33.77       35.43          35.43
    # SEX
    #   F                     79           77             66
    #   M                     51           55             60
    #   U                      3           2              4
    #   UNDIFFERENTIATED       1           0              2

## Converting the Table to a Result Data Frame (ARD)

The `as_result_df()` function is used to convert a table to a result data frame. The result data frame is a data frame that contains the result of the summary table and is ready to be used for quality control purposes. This may be customized according to different standards.

Let’s see how we can produce different result `data.frame`s. The following outputs can be returned by setting different parameters in the `as_results_df()` function, and these results can be transformed back into a table using the `df_to_tt()` function.

    as_result_df(tbl)
    #   avar_name         row_name       label_name row_num is_group_summary
    # 1       AGE             Mean             Mean       2            FALSE
    # 2       SEX                F                F       4            FALSE
    # 3       SEX                M                M       5            FALSE

Now let’s generate our final ARD output, which is ready to be used for quality control purposes.

    as_result_df(tbl, make_ard = TRUE)

## Customizing the Output

`as_result_df()` and ARDs depend on the content of the table, so it is possible to modify the table to customize the output. For example, we can add some user-defined statistics with custom names:

    # rcell and in_rows are the core of any analysis function
    rc <- rcell(c(1, 2), stat_names = c("Rand1", "Rand2"))
    print(obj_stat_names(rc)) # c("Rand1", "Rand2")
    # [1] "Rand1" "Rand2"

    rc_row <- in_rows(
      .list = list(a = c(NA, 1), b = c(1, NA)),
      .formats = c("xx - xx", "xx.x - xx.x"),
      .format_na_strs = list(c("asda", "lkjklj")),
      .stat_names = list(c("A", "B"), c("B", "C"))
    )

    # Only a getter for this object
    print(obj_stat_names(rc_row)) # list(a = c("A", "B"), b = c("B", "C"))
    # $a
    # [1] "A" "B"
    #
    # $b
    # [1] "B" "C"

    # if c("A", "B"), one for each row
    # if single list, duplicated
    rc_row <- in_rows(
      .list = list(a = c(NA, 1), b = c(1, NA)),
      .formats = c("xx - xx", "xx.x - xx.x"),
      .format_na_strs = list(c("asda", "lkjklj")),
      .stat_names = c("A", "B")
    )
    print(obj_stat_names(rc_row)) # c("A", "B") # one for each row
    # $a
    # [1] "A"
    #
    # $b
    # [1] "B"
    print(lapply(rc_row, obj_stat_names)) # identical to above + row names
    # $a
    # [1] "A"
    #
    # $b
    # [1] "B"

    rc_row <- in_rows(
      .list = list(a = c(NA, 1), b = c(1, NA)),
      .formats = c("xx - xx", "xx.x - xx.x"),
      .format_na_strs = list(c("asda", "lkjklj")),
      .stat_names = list(c("A", "B")) # It is duplicated, check it yourself!
    )

Let’s put it into practice:

    mean_sd_custom <- function(x) {
      mean <- mean(x, na.rm = FALSE)
      sd <- sd(x, na.rm = FALSE)

      rcell(c(mean, sd),
        label = "Mean (SD)", format = "xx.x (xx.x)" # ,
        # stat_names = c("Mean", "SD")
      )
    }
    counts_percentage_custom <- function(x) {
      cnts <- table(x)
      out <- lapply(cnts, function(x) {
        perc <- x / sum(cnts)
        rcell(c(x, perc), format = "xx. (xx.%)")
      })
      in_rows(
        .list = as.list(out), .labels = names(cnts),
        .stat_names = list(c("Count", "Percentage"))
      )
    }

    lyt <- basic_table(show_colcounts = TRUE, colcount_format = "N=xx") %>%
      split_cols_by("ARM", split_fun = keep_split_levels(c("A: Drug X", "B: Placebo"))) %>%
      analyze(vars = "AGE", afun = mean_sd_custom) %>%
      analyze(vars = "SEX", afun = counts_percentage_custom)

    tbl <- build_table(lyt, ex_adsl)

    as_result_df(tbl, make_ard = TRUE)
    #    group1 group1_level variable   variable_level   variable_label  stat_name

# More Complex Outputs

Let’s add hierarchical row and column splits:

    lyt <- basic_table() %>%
      split_rows_by("STRATA2") %>%
      summarize_row_groups() %>%
      split_cols_by("ARM") %>%
      split_cols_by("STRATA1") %>%
      analyze(c("AGE", "SEX"))

    tbl <- build_table(lyt, ex_adsl)

    as_result_df(tbl, make_ard = TRUE)
    #      group1 group1_level group2   group2_level  group3 group3_level variable
