如何以编程方式获取当前文件的 Knit 目录？

Question

In the current version (1.2.5001) of RStudio, there are 2 ways to set the Knit directory (working directory for R Markdown files). See Fig. 1 and Fig. 2.

Fig. 1 The global option to set the default Knit directory in RStudio.

Fig. 2 The way to set the Knit directory for an individual file.

You can use the following code to retrieve the Global option from Fig. 1:

.rs.readUiPref("knit_working_dir")

The question: how can the Knit directory of an individual file (which was set in Fig. 2) be retrieved programmatically?
