Text formatting of lists in Pandoc's Markdown

Question

I've added asterisks and a new line break to the sampleList elements in order to create a bulleted list format:


sampleList <- list(1, 2, 3)

# Create bulleted list
createPoints = function(list) {
  # Pre-allocate list
  setList <- vector(mode = "list", length = length(list))

  # Add elements to each line
  for (i in seq_along(list)) {
    line = sprintf("* %s  \n", list[[i]])
    setList[[i]] <- line
  }
  
  return(setList)
}

finalList = createPoints(sampleList)

Output:

[[1]]
[1] "* 1  \n"

[[2]]
[1] "* 2  \n"

[[3]]
[1] "* 3  \n"

How do I print the individual elements in a bulleted sublist?

This does not work:

Bullet 1
- r finalList

My output comes with extra commas and no bullets for the sublists:

Bullet 1
- 1
, * 2

, * 3

I would like it to look like this:

Bullet 1
- 1
- 2
- 3

you could install `pander` instead and use it ie `pander::pander(sampleList)` — Onyambu, Aug 01 '20 at 01:00

Unlist your finalList object and collapse all elements together to avoid commas

sampleList <- list(1, 2, 3)

# Create bulleted list
createPoints = function(list) {
  # Pre-allocate list
  setList <- vector(mode = "list", length = length(list))

  # Add elements to each line
  for (i in seq_along(list)) {
    line = sprintf("* %s  \n", list[[i]])
    setList[[i]] <- line
  }
  
  return(setList)
}

finalList = unlist(createPoints(sampleList))

r paste(finalList, collapse = " ")

This was helpful, thanks! I had to adjust the sprintf to have two spaces in front of the asterisk in order to indent properly. – SRL Aug 02 '20 at 02:38
