Question

我正在使用rmarkdown自动执行pdf报告。我使用宏来运行代码。我可以运行一次代码，并且可以正常运行。当我再次调用该宏时，它似乎可以工作，但是在创建pdf时，出现错误“ LaTeX错误：缺少\ begin {document}”

这是我第一次得到：

output file: L:/Statunit/morton/NCC R markdown reports/NCC Reports/NCC_Dashboard_Report_Dave.knit.md

"C:/Program Files/RStudio/bin/pandoc/pandoc" +RTS -K512m -RTS "L:/Statunit/morton/NCC R markdown reports/NCC Reports/NCC_Dashboard_Report_Dave.utf8.md" --to latex --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output pandoc9e03c3032cf.tex --template "C:\Users\Mortond\Documents\R\win-library\3.5\rmarkdown\rmd\latex\default-1.17.0.2.tex" --highlight-style tango --latex-engine xelatex --variable graphics=yes --variable "geometry:margin=1in" --variable "compact-title:yes" --include-in-header "C:\Users\Mortond\AppData\Local\Temp\Rtmp8cWvvQ\rmarkdown-str9e022b75c22.html" 

Output created: Report-254-225573.pdf

第二次，我调用了相同的代码，但是只更改了报表名称，因此数据相同，我得到了。

output file: L:/Statunit/morton/NCC R markdown reports/NCC Reports/NCC_Dashboard_Report_Dave.knit.md

我的YAML是

    - \usepackage{fancyhdr}
    - \addtolength{\headheight}{1.0cm} % make more space for the header

my code that calls the markdown is :
    render_report = function(b,h,p) {
      rmarkdown::render(
       "L:/Statunit/morton/NCC R markdown reports/NCC Dashboard Report 
          Dave.Rmd", params = list(
          b1 = b,
          h1 = h,
         p1 = p
        ),
        output_file = paste0("Report-", h, "-", p, ".pdf")
      )
    }

    render_report(b="xxxx Hospital, Inc.",h='253',p='225573')

那么为什么它只能工作一次而不是第二次？如果退出RStudio，然后再次启动它，它似乎可以正常工作。我尝试过
.rs.restartR()无济于事。以及 rm(list = ls(envir = globalenv()),envir = globalenv()) gc()进行清理。

有什么想法吗？我很感谢阅读所有这些内容。

我不知道我是否有同样的问题。但是我经历过，如果我编译文档，它将在第一次工作，而第二次失败。我怀疑存在缓存问题，并将cache.rebuild=T添加到了

<<echo=F, cache=T, message=F, warning=F, `>>= set_parent('../../Parent.Rnw') @

仅供参考，父级的标头不仅包含乳胶信息，还提供计算的主.R文件。

无论如何，如果有人遇到类似的问题，请尝试将cache.rebuild=T添加到您包含的脚本中。

另一个LaTeX错误：rmarkdown中缺少\ begin {document}
