在 rmarkdown 中渲染 fusionchartsR htmlwidgets

Question

我正在构建一个名为 fusionchartsR (https://github.com/alexym1) 的新 htmlwidget 包。我试图在我的 rmarkdown 报告中嵌入一小段代码，但是它不起作用，我不知道为什么。我尝试了不同的策略但没有成功。

第一策略

---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## Render an htmlwidget graphic

```{r}
library(fusionchartsR)
df <- data.frame(label = c("Venezuela", "Saudi", "Canada", "Russia"), value = c(290, 260,180, 115))
fusionPlot(data = df, type = 'pie2d') %>%
  fusionTheme(theme = "fusion") 
```

第二个策略

# Webshot and phantomjs have been previously installed.
library(webshot)
webshot::install_phantomjs()

# Then, I loaded packages and built a little piece of code
library(fusionchartsR)
library(htmlwidgets)

df <- data.frame(label = c("Venezuela", "Saudi", "Canada", "Russia"), value = c(290, 260,180, 115))
widget <- fusionPlot(data = df, type = 'pie2d') %>%
  fusionTheme(theme = "fusion") 

# Save a rendered widget to an HTML file
saveWidget(widget = widget, file = "Mywidget.html")

# An error appeared: `Error: pandoc document conversion failed with error 99`

# Take a webshot
webshot(url = "Mywidget.html", file = "webshot.png")

Mywidget.html 可以在您的 Documents 文件夹中找到。

我该如何解决这个问题？ 我会很感激的！

Answer 1

您应该考虑在https://github.com/rstudio/webshot2 上尝试webshot2，而不是使用 webshot，它不会遇到此问题。我已经使用 webshot2 复制了您的场景，问题已解决，如下图所示。类似情况见my detailed answer。

代码：

# Webshot and phantomjs have been previously installed.
library(webshot2)

# install.packages("remotes")
# remotes::install_github("alexym1/fusionChartsR")

# Then, I loaded packages and built a little piece of code
library(fusionchartsR)
library(htmlwidgets)

df <- data.frame(label = c("Venezuela", "Saudi", "Canada", "Russia"), value = c(290, 260,180, 115))
widget <- fusionPlot(data = df, type = 'pie2d') %>%
  fusionTheme(theme = "fusion") 

# Save a rendered widget to an HTML file
saveWidget(widget = widget, file = "Mywidget.html")

# An error appeared: `Error: pandoc document conversion failed with error 99`

# Take a webshot
webshot(url = "Mywidget.html", file = "webshot.png")

输出：
