Example 17: Code Insertion"

In reporter: Creates Statistical Reports

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

The reporter package allows users to insert code directly with report_options(allow_code = TRUE). This feature is currently available only for RTF and HTML outputs.

Insert RTF Code{#rtf}

The reporter package let's you insert RTF code in data sets, titles, footnotes, headers, and footers.

Let's prepare a data set with RTF code:

df <- read.table(header = TRUE, text = '
      var     label        A             B
      "ampg"   "\\li360 N"          "19"          "13"
      "ampg"   "\\li360 Mean"       "18.8"  "22.0 (4.9)"
      "ampg"   "\\li360 Median"     "16.4{\\sub mm}"        "21.4{\\super 2}"
      "ampg"   "\\li360 {\\cf12 Q1 - Q3}"    "15.1 - 21.2" "19.2 - 22.8"
      "ampg"   "\\li360 Range"      "{\\cf2 10.4 - 33.9}" "14.7 - 32.4"
      "cyl"    "\\li360 8\\line Cylinder" "\\ul 10 ( 52.6%) \\ul0" "4 ( 30.8%)"
      "cyl"    "\\li360 6\\line {\\cf11 Cylinder and more perhaps more}" "4 ( 21.1%)"  "3 ( 23.1%)"
      "cyl"    "\\li360 4\\line Cylinder" "\\ul 5 ( 26.3%) \\ul0"  "6 ( 46.2%)"')

Observe that there are several RTF formatting codes in the data set:

• Indentation with \\li
• Subscript and Superscript with \\sub and \\super
• Coloring with \\cf
• Underline with \\ul

Now let's do some more manipulation of the RTF in the reporter code:

fp <- file.path(tempdir(), "example17.rtf")

# Create table
tbl <- create_table(df, first_row_blank = TRUE, borders = c("all")) |>
  stub(c("var", "label"), width = .8) |>
  define(var, blank_after = TRUE, label_row = TRUE,
         format = c(ampg = "\\i Here is a italic label \\i0.", 
                    cyl = "\\ul Under line label \\ul0")) |>
  define(A, label = "\\shad {{\\cf6 Group A}} {common::supsc('2')}\\shad0", align = "center", n = 19) |>
  define(B, label = "\\outl Group B \\outl0", align = "center", n = 13) |>
  footnotes("\\i\\fs14 * Italic Small Table Footnote \\fs18")

# Create report and add content
rpt <- create_report(fp, orientation = "portrait", output_type = "RTF",
                     font = "Times") |>
  report_options(allow_code = TRUE) |>
  page_header(left = "\\strike Strikethrough header \\strike0", right = "Study: Cars") |>
  titles("\\b\\i {{\\highlight7 This is yellow italic highlight}} \\b0\\i0", 
         "\\fs0\\fs28 {{\\cf2 This is a blue big title}} \\fs18") |>
  add_content(tbl) |>
  footnotes("\\i\\fs14 * Italic Small Report Footnote \\fs18") |>
  page_footer(left = "Left",
              center = "Confidential",
              right = "Page [pg] of [tpg]")

Note that in the reporter package, curly braces are normally reserved for the glue replacement feature. Therefore, if you want to use curly braces as part of your RTF code insertion, they must be doubled, i.e.{{\\cf6 Group A}}. The single curly braces will still be available as glue replacements.

Here is the result:

As seen above, all the RTF code insertion worked as expected:

• Header is formatted with strike through.
• Titles are formatted with yellow highlight, italic, bold, blue color, and bigger font size.
• Column labels are formatted with red, shadow, and outline.
• Row labels are formatted with italic and underline.
• Subscript and superscript are displayed.
• Data values are formatted with blue, purple, underline, and indentation.
• Footnotes are formatted with italic and smaller font size.

RTF Color Table

The above example contains several references to the RTF color table. Here is the complete color table:

• \cf1 : Black
• \cf2 : Blue
• \cf3 : Cyan
• \cf4 : Lime Green
• \cf5 : Magenta
• \cf6 : Red
• \cf7 : Yellow
• \cf8 : White
• \cf9 : Navy Blue
• \cf10 : Teal
• \cf11 : Green
• \cf12 : Purple
• \cf13 : Maroon/ Dark Red
• \cf14 : Olive
• \cf15 : Gray
• \cf16 : Light Gray

The above color references are the same as those used by SAS ODS RTF.

Insert HTML Code{#html}

The reporter package also allows you insert HTML code in data sets, titles, footnotes, headers, and footers.

Let's prepare a data set with HTML code:

Now let's do some more manipulation of the HTML in the reporter code:

fp <- file.path(tempdir(), "example17b.html")

# Create table
tbl <- create_table(dat, borders = "outside") %>%
  titles('<p style="color: blue; font-size: 18px;">Blue 18 px <b>Title</b>: Page [pg] of [tpg]</p>',
         "<b>Bold table title</b>") %>%
  footnotes("<i>Italic footnote: Page [pg] of [tpg]</i>", "Emphasize <sup>Super</sup>") %>%
  define(var, label = "Name") %>%
  define(A, label = "Treatment A mg<sup>2</sup>") %>%
  define(B, label = "Treatment B mg<sup>2</sup>")

# Create Report
rpt <- create_report(fp, output_type = "html", font = fnt,
                     font_size = fsz, orientation = "landscape") %>%
  report_options(allow_code = TRUE) %>%
  set_margins(top = 1, bottom = 1) %>%
  add_content(tbl) %>%
  add_content(tbl) %>%
  titles("<mark>Mark Title: Page [pg] of [tpg]</mark>") %>%
  footnotes("<small>Small footnote</small>: Page [pg] of [tpg]", borders = "none") %>%
  page_header('<code style="color:red;">Code Style Page [pg] of [tpg]</code>',
              right = '<del>Strikethrough</del>') %>%
  page_footer("Footer: Page <sub>[pg]</sub> of [tpg]",
              right = "Footer: Page <sub>[pg]</sub> of [tpg]")

res <- write_report(rpt)

As seen above, all the HTML code insertion worked as expected:

• Headers are formatted with red code style and strike through.
• Titles are formatted with yellow highlight, blue 18px, and bold.
• Column headers are formatted with superscript.
• Data values are formatted with underline, indentation, color, bold, and background color.
• Footnotes are formatted with italic, superscript, and smaller font size.
• Footers are formatted with subscript.
