项目build出错。

[icejean]

Hi,大家好， 最近在学习R markdown，了解到这本正在写作中的书，下载了项目尝试build一下，有几个小问题反馈一下。 1、 01-intro.Rmd 1)、images/01-notebook-preview.jpg应改为images/01-notebook-preview.png，并重命名文件， png格式。

knitr::include_graphics("images/01-notebook-preview.png")

2、images/01-dynamic-document.jpg应改为images/01-dynamic-document.png，并重命名文件， png格式。

knitr::include_graphics("images/01-dynamic-document.png")

2、build HTML与word都可以，但build PDF出错，不知到写作团队测试过build PDF没有。我是菜鸟，还无法定位解决问题。不过知道PDF中laTeX数学公式等的效果比Word要方便很多和好很多。

Thanks for your comment. PDF is failed in my computer too, I don't find out a solution for this now.

这个错误应该是这一行导致的，注释掉之后是其他错误

你直接在Rstudio中展开错误之处的stack trace就可以定位到这一行了，不过怎么解决？8-）

bookdown::render_book('index.Rmd',"bookdown::pdf_book")
