The tbl data frame is the main input to the
gentlg function for creating the RTF/HTML outputs. This
vignette will show you the tbl structure and how the
tbl variables are in action for rendering the RTF/HTML
outputs.
The basic variables of tbl includes label, col1, col2, …, coln, where
label: row text displayed on the 1st column of the table
col1: statistic results displayed on the 2nd column of the table
col2: statistic results displayed on the 3rd column of the table.
The example below shows you a very basic tbl data frame, and how this
tbl is transformed through the gentlg function call to
create the HTML output.
library(dplyr)
library(tidytlg)
tbl <- tibble::tribble(
~label, ~col1, ~col2, ~col3,
"Analysis Set: ITT", "86", "84", "84",
"Age (Years)", NA, NA, NA,
"N", "86", "84", "84"
)
knitr::kable(tbl)| label | col1 | col2 | col3 |
|---|---|---|---|
| Analysis Set: ITT | 86 | 84 | 84 |
| Age (Years) | NA | NA | NA |
| N | 86 | 84 | 84 |
# render tbl
gentlg(huxme = tbl,
format = "HTML",

wcol = .30)

#> Column names: label, col1, col2, col3The above example does not have any formatting in actions on the
table. To enable formatting, additional variables will need to be
created in the tbl data frame.
For inserting a blank line prior to the 2nd row (i.e. Age (Years)),
we will need to add the newrows variable with value =
1.

add the indentme variable with value = 1, which indicates 1
indentation (2 will result in 2 indentation, and so on).

#> Column names: label, col1, col2, col3There is another formatting variable called newpage,
where assigning newpage = 1 will start a new page in the
output.
Besides manually adding the formatting variables to tbl,
we have developed several formatting functions to facilitate the
formatting process:
add_newrows: add newrows variable to
the tbl based on row_type
add_indent: add indentme variable to
the tbl based on row_type
add_newpage: add newpage variable to
the tbl based on row_type.
The row_type variable is created in the tbl by calling
the freq, nested_freq, and univar
functions, which is used by the above functions for setting up the
formatting variables. The tbl example below is obtained by
calling the univar function for summarizing the age
statistics in the CDISC ADSL dataset. After calling the
univar function, we create the anbr (analysis
number) variable as the identifier of this tbl chunk.
tbl <- cdisc_adsl %>%
univar(colvar = "TRT01PN",
rowvar = "AGE",
statlist = statlist(c("N", "MEANSD")),
decimal = 0,
row_header = "Age (Years)") %>%
mutate(anbr = "01")
knitr::kable(tbl)| label | 0 | 54 | 81 | row_type | group_level | anbr |
|---|---|---|---|---|---|---|
| Age (Years) | HEADER | 0 | 01 | |||
| N | 5 | 5 | 5 | N | 0 | 01 |
| Mean (SD) | 69.6 (14.40) | 75.6 (6.73) | 72.2 (9.23) | VALUE | 0 | 01 |
The add_format function, which incorporates all 3
formatting functions above (add_indent,
add_newrows, add_newpage), can then be applied
to the tbl for creating the formatting variables.
tbl <- cdisc_adsl %>%
univar(colvar = "TRT01PN",
rowvar = "AGE",
statlist = statlist(c("N", "MEANSD")),
decimal = 0,
row_header = "Age (Years)") %>%
mutate(anbr = "01") %>%
add_format()
knitr::kable(tbl)| label | 0 | 54 | 81 | row_type | anbr | indentme | roworder | newrows | newpage |
|---|---|---|---|---|---|---|---|---|---|
| Age (Years) | HEADER | 01 | 0 | 1 | 0 | 0 | |||
| N | 5 | 5 | 5 | N | 01 | 1 | 2 | 0 | 0 |
| Mean (SD) | 69.6 (14.40) | 75.6 (6.73) | 72.2 (9.23) | VALUE | 01 | 2 | 3 | 0 | 0 |
