html R Markdown中不显示数字

Question

我对R Markdown和knitr相当陌生。

我想在我的报告中添加一些数字:

![my figure](/figure/another_folder/my_picture.png)

假设/figure/another_folder/在当前工作目录下。但是我的报告里没有数字，只有问号。

系统信息:

我还发现了运行诊断报告的建议(在r-studio支持页面上):

> rstudio::diagnosticsReport()
Error: package ‘rstudio’ was built before R 3.0.0: please re-install it

可以连接吗?如果是这样，我应该如何重新安装R-studio?我的卸载。app?因为运行install.packages('rstudio')只会产生警告:Warning message: package ‘rstudio’ is not available (for R version 3.0.1)

Answer 1

问题是第一个斜杠。如果我这样写:

![my figure](figure/another_folder/my_picture.png)

一切都很好。对不起，我误读了手册!
