Tips & Tricks: Including Symbols, Superscripts, Subscripts & Line Breaks

Symbols

Symbols can be added to the label column via unicode. Here is a quick reference to commonly used symbols.

Symbol	Textual Description	Unicode
←	Left arrow	\u2190
→	Right arrow	\u2192
≤	Less-than or equal to	\u2264
≥	Greater-than or equal to	\u2265
≠	Not equal to	\u2260
±	Plus-minus sign	\u00b1
α	Alpha	\u03b1
β	Beta	\u03b2
μ	Mu	\u03bc
«	Non-breaking space	\u00ab

Here is an example call to tidytlg::gentlg() that will add the symbols to the label column.

df <- tibble::tibble(
  label = c("\u2264", "\u2265"),
  col1 = c("100", "200")
)

tidytlg::gentlg(df,
                file = "demo")

Superscripts and Subscripts

Superscripts and Subscripts can be added to the label column via unicode.

df <- tibble::tibble(
  label = c("This is a superscript a{\\super a}",
            "This is a subscript b{\\sub b}"),
  col1 = c("100", "200")
)

tidytlg::gentlg(df,
                file = "demo")

Superscripts and Subscripts can be added to the footnotes via unicode as well.

df <- tibble::tibble(
  label = c("This is a superscript a{\\super a}",
            "This is a subscript b{\\sub b}"),
  col1 = c("100", "200")
)

tidytlg::gentlg(df,
                file = "demo",
                footers = "This is a footnote superscript{\\super a}")

Inline RTF Line Breaks

Sometimes you need add a line break into your RTF. Inserting ‘\\\n’ into your string will add your line break for you.

df <- tibble::tibble(
  label = c("Bodysystem \\\n Preferred Term"),
  col1 = c("100")
)

tidytlg::gentlg(df,
                file = "demo")

If you need a line break followed by a tab, just add in ‘\\li180’.

df <- tibble::tibble(
  label = c("Bodysystem\\\n\\li180Preferred Term"),
  col1 = c("100")
)

tidytlg::gentlg(df,
                file = "demo")
