R: Correctly Using the "rmarkdown::render()" Function-CodePudding

I am working with the R programming language.

My Question: I am trying to learn how to use the rmarkdown::render() function in R.

For example, suppose I have the following R Markdown Code:

---
title: "Storyboard Commentary"
output: 
  flexdashboard::flex_dashboard:
    storyboard: true
---

### A nice scatterplot here

```{r}
plot(cars, pch = 20)
grid()
```

---

Some commentary about Frame 1.

### A beautiful histogram on this board

```{r}
hist(faithful$eruptions, col = 'gray', border = 'white', main = '')
```

---

Some commentary about Frame 2.

I copied and pasted the above code into a Notepad document - and then saved this file as "test_render.Rmd".

Now, I want to use the render() function to execute this file, e.g. rmarkdown::render("test_render.Rmd") - but I am not sure how I can import this file into R using code (i.e. without manually clicking/pointing on the file).

The reason I am asking about this, is because I am using a computer at school where we only have the older GUI version of R (i.e. we do not have R Studio) and I would like to directly import an .Rmd file into R and use this render() function, and create the final result.

Can someone please show me how to do this?

Thanks!

You should be able to render the rmarkdown file and export it using the input and output arguments of render, i.e.

rmarkdown::render(input = "test_render.Rmd", output_file = "test_render.html")

It should save in your current working directory.
