Add mathematical notation (dot above letter) to flextable

Question

I would like to add mathematical notation: to my flextable.

This is my mwe and attempt:

df = data.frame(item = c("vo2", "age"),
                mean = c(30,40))
df

flextable(df)%>%
  mk_par(i=1, j=1, as_paragraph(" $\dot{V}$O", as_sub(2peak) ))
# also attempted

flextable(df)%>%
  mk_par(i=1, j=1, as_paragraph(as_equation($\dot{V}$O), as_sub(2peak) ))

Answer 1

You need to use as_equation() that expects MathJax syntax:

library(flextable)
df <- data.frame(
  item = c("vo2", "age"),
  mean = c(30, 40)
)

flextable(df) |>
  mk_par(i = 1, j = 1, as_paragraph(
    as_equation("\\dot{V}0_{2peak}")
  ))
