r - Pandoc 的 Markdown 中列表的文本格式

Question

为了创建项目符号列表格式，我在 sampleList 元素中添加了星号和新的换行符：

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)

输出：

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

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

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

如何打印项目符号子列表中的各个元素？

这不起作用：

• 子弹 1
  • r finalList

我的输出带有额外的逗号，子列表没有项目符号：

• 子弹 1

  • 1

  , * 2

  , * 3

我希望它看起来像这样：

• 子弹 1
  • 1
  • 2
  • 3

取消列出您的finalList对象并将所有元素折叠在一起以避免逗号

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 = " ")
