rmarkdown文件(.Rmd)的html在浏览器中未正确显示 [英] html of rmarkdown file (.Rmd) is not displayed correctly in browser

问题描述

当我将.Rmd编织为html时，它无法正确显示. e.格式似乎有问题(请参见下面的屏幕截图):这两个超链接不起作用，字体不是sans-serif，没有目录，等等.我在6个月的不同机器上使用了相同的代码之前，它按预期呈现.但是，今天没有.有谁知道为什么html看起来丑陋?似乎不依赖于我打开html的浏览器(在IE和Chrome中测试过).

When I knit my .Rmd to html, it does not get displayed properly, i. e. it seems like something is wrong with the format (see screenshot below): The two hyperlinks do not work, the font is not sans-serif, there is no table of contents, etc. I used the same code on a different machine 6 months ago and it rendered as expected. However, today it does not. Does anybody have an idea why the html looks ugly? It seems not to depend on the browser I open the html with (tested it in IE and Chrome).

这是我使用的代码:

---
title: "my title"
author: "subtitle"
date: "my name, `r format(Sys.time(), '%d. %B, %Y')`"
output:
  html_document:
    code_folding: hide
    highlight: haddock
    number_sections: yes
    toc: yes
    toc_float: yes

更新:在Chrome中打开html，按F12，然后在控制台下显示

update: Opened the html in Chrome, pressed F12, and under console it says

推荐答案

我的一个朋友找到了解决此问题的方法:我们公司中的.libPaths()被定义为

A friend of mine got the solution for this problem: The .libPaths() in our company was defined as

.libPaths()
#> [1] "\\\\userhome/my_user_name/R/win-library/3.4"   # note the four \\\\
#> [2] "C:/Program Files/R/3.4.2/library"

将第一个位置更改为

.libPaths()
#> [1] "C:/Users/my_user_name/R/win-library/3.4.2"     # path starts with C:/
#> [2] "C:/Program Files/R/3.4.2/library"

.Rmd呈现预期的效果:).

the .Rmd renders as expected :).

我们在 .Rprofile 中放置了以下功能.它会逐步创建目录并将其添加到.libPaths().

We placed the following function in our .Rprofile. It creates the directory step-by-step and adds it to .libPaths().

# install packages locally within user profile
(function() {
  components <- list('C:/', 'users', Sys.info()['login'], 'R',
                     'win-library', paste0(R.Version()$major,
                                           '.',
                                           R.Version()$minor))

  # loop over components and create dir step-by-step
  # (recursive = TRUE leads to errors)
  for (k in 4:length(components)) {
    p <- do.call(file.path, components[1:k])
    dir.create(p, showWarnings = FALSE, recursive = FALSE)
  }

  path <- do.call(file.path, components)
  .libPaths(c(path, .Library))
})()
