Here is my approaches/cheat-sheet/template:

If have codes like these:
 

     library("xxx")    

     summary (usmort)

 

Method I (using RStudio)

• Start a new R markdown file (File -> New File-> R Markdown).
• Delete all the codes that RStudio generated in that new file.
• Copy and paste the R codes above into the new file
• Add global option (between --- and ---), chunk head (```) with option (eval=FALSE), and chunk tail (```) :

    ---

    output:

    word_document:

    highlight: pygments

    ---

    ```{r,eval=FALSE}

                 ... your codes here ...

    ``` 

• Click the ‘knit word’ button, you get a Word file with codes show like below: 

     library("xxx")
     summary (usmort)

 

Method II (with or without using RStudio)

• add chunk head (```{r,eval=FALSE}) and tail (``` ) and wrap the whole codes, and save the file ("xxx_r_code.R").
• run the R commands in console window:

       >library(rmarkdown)

    >render("xxx_r_codes.R",word_document(highlight="pygments"))
