Building a manuscript table end to end • hvtiRtables

library(hvtiRtables)

This walks one complete manuscript table, from a data frame to a checked .docx, and then lays the same table out to describe its groups side by side. The report path is shorter and covered in ?hv_man_table.

1. Summarize the data

hv_tbl_summary() takes a grouped, ordered variable list and type buckets, the way the SAS %summarytable macro does. Every variable in groups appears in exactly one of continuous, binary, or categorical.

tbl <- hv_tbl_summary(
  gtsummary::trial,
  by = "trt",
  groups = list(
    Demography = c("age", "marker"),
    Disease = c("stage", "grade")
  ),
  continuous = c("age", "marker"),
  categorical = c("stage", "grade"),
  compare = "pvalue"
)

The result records what the manuscript style reads: the statistic it shows and the comparison column.

attr(tbl, "hv_stat_label")
#> [1] "No. (%) or Median [15th, 85th percentiles]"
attr(tbl, "hv_trailing")
#> hv_compare_col 
#>            "P"

2. Shape the manuscript table

ft <- hv_man_table(tbl, style = "manuscript")

The "compare" layout, the default, for groups the table compares: one overall n column, the grouping spanning its levels, and the P column.

3. Or describe the groups side by side

ft2 <- hv_man_table(tbl, style = "manuscript", layout = "describe")

The "describe" layout gives each group its own count, for separate cohorts or repeated measures. The P column stays, because the table carries it. Either layout names the tests behind the p-values in its dagger note, so there is no separate step for test footnotes.

4. Save and check

out <- tempfile(fileext = ".docx")
hv_man_table_save(
  ft, out,
  caption = "Table 1. Baseline Characteristics",
  abbreviations = c(SMD = "standardized mean difference")
)

Neither saver checks its own output, so run hv_check_docx() on the path, as the style that wrote it. Zero rows means clean.

hv_check_docx(out, style = "manuscript")
#> [1] type     table    location detail  
#> <0 rows> (or 0-length row.names)

What the package refuses

Every public function rejects out-of-spec input with a message naming the fix, rather than letting it reach gtsummary or flextable.

hv_man_table(
  gtsummary::tbl_summary(gtsummary::trial, by = "trt", include = "age"),
  style = "manuscript"
)
#> Error:
#> ! style = "manuscript" needs a table from hv_tbl_summary(), which carries each variable's overall count for the n column.

hv_tbl_summary(
  gtsummary::trial, groups = list(D = "age"),
  continuous = "age", binary = "age"
)
#> Error:
#> ! `age` appears in more than one of `continuous`, `binary`, and `categorical`. Every variable must be classified exactly once. Overlapping: age (continuous, binary).
