Export euler plot to powerpoint

I have an euler plot created with eulerr package.

Sample data:

fit <- euler(c(
   "A" = 10000,
   "B" = 7000,
   "A&B" = 600))

plot(fit,
     quantities = list(fontsize = 9),
     fills = c("#8ABDAF", "#DC8E8D"),
     fontsize = 9,
     main  = list(label = "Title"),
     labels = NULL,
     legend = list(labels = c("A", "B"))
     )

enter image description here

I want to export this base R plot to powerpoint not as an image but in a way where I can modify each element.

As it's not a ggplot, I can't export using export package. But it does seem like there is a possibility with a combination of the officer and rvg packages.

I've seen another thread using the function ph_with_vg from the rvg package, but after installing rvg that function is not existing.

I tried the following:

read_pptx() %>% 
  add_slide(layout = "Title and Content", master = "Office Theme") %>% 
  ph_with(dml(code = {
    plot(fit)
  }), 
  location = ph_location_type(type = "body")) %>% 
  print(target = "Euler_fit.pptx")

But I get the error:

Error in read_xml.raw(charToRaw(enc2utf8(x)), "UTF-8", ..., as_html = as_html,  : 
  StartTag: invalid element name [68]

I have no idea what that means.

Does anybody know how to do this?

Thanks.

Solution

  • Note that this is a grid plot and not a base plot.

    You are just missing a plot statement:

    library(eulerr)
library(rvg)
library(officer)

fit <- euler(c(
  "A" = 10000,
  "B" = 7000,
  "A&B" = 600))

p <- plot(fit,
     quantities = list(fontsize = 9),
     fills = c("#8ABDAF", "#DC8E8D"),
     fontsize = 9,
     main  = list(label = "Title"),
     labels = NULL,
     legend = list(labels = c("A", "B"))
)


read_pptx() |> 
  add_slide(layout = "Title and Content", master = "Office Theme") |> 
  ph_with(dml(code = {
    plot(p)
  }), 
  location = ph_location_type(type = "body")) |> 
  print(target = "Euler_fit.pptx")
