在RMarkdown中创建图并编织为HTML的功能不起作用 [英] Function to create plot and knit to HTML in RMarkdown not working

问题描述

我在这个问题上陷入困境.我在r markdown文档中有一个功能.该函数采用案例编号"作为参数.变量，该变量用于过滤某些数据帧，生成图并将其输出到编织的html文档中.这是基本概念:

I'm stuck on this problem. I have a function in a r markdown document. The function takes a "case number" variable, which is used to filter some data frames, produce a plot, and output the plot to a knit html document. Here's the basic idea:

---
title: "Plot"
output: 
  html_document:
    toc: true
    toc_float: true
    toc_depth: 2

---

```{r echo=FALSE, results='hide',message=FALSE,warning=FALSE}

library(dplyr)
library(ggplot2)
library(scales)
library(lubridate)
library(plotly)
library(vistime)



```

```{r echo = FALSE, warning=FALSE, fig.align='CENTER', fig.width=10, fig.height=5}

#event_id <- "category 1"
build_plot <- function(event_id) {
   data.filtered <- data%>%
    filter(group==event_id)

   p <- vistime(data.filtered)
   pb <- plotly_build(p)
   pb #Display plot
   
   rmarkdown::render(input = "stack_overflow_example.Rmd",
                  output_format = "html_document",
                  output_file = 'stack_overflow_example.html',
                  output_dir = "//mydir/myfolder")
}

build_plot("category 1")                        
 
```

我收到此错误，并且没有文档输出:

I'm getting this error, and no document is output:

Error in sink(con, split = debug) : sink stack is full

任何帮助表示赞赏.

推荐答案

在文档上运行render与将html编织在一起的功能相同.这包括运行文档中的所有R代码.

Running render on a document does the same thing as knit to html. That includes running all the R code in the document.

但是您不应该在文档本身中放入render-您创建了一个递归循环，因为您在文档上调用了render，从而在文档上运行了代码，在文档上调用了render，然后在文档上运行了render文件中的代码....

But you shouldn't put render in the document itself - you've created a recursive loop because you call render on the document, which runs the code on the document, which calls render on the document, which runs the code in the document....

从文档中删除render调用，而不是将其放在单独的R脚本中.然后，运行该脚本将呈现文档.

Remove the render call from your document, instead put it in a separate R script. Then, running that script will render the document.
