Testing R Markdown Formats

1 Test File of R Markdown

1.1 R Notebook

This is an R Markdown file ‘test-rmarkdown.Rmd’ with various output formats, created using ‘RNotebook_Template.Rmd’. When you execute or run a code within the notebook, the results appear beneath the code.

Try executing this chunk by clicking the Run button, a triangle pointing right, within the chunk or by placing your cursor inside it and pressing Ctrl+Shift+Enter (Win) or Cmd+Shift+Enter (Mac).

1.2 Test Code Chunk (1)

head(cars)

1.3 Test Code Chunk (2)

plot(cars)

1.4 Test Code Chunk (3)

knitr::kable(iris[1:6, ])

1.5 Test Code Chunk (4)

ggplot(iris, aes(x = Petal.Length, y = Petal.Width, col = Species)) +
  geom_point()

1.6 New Code Chunk

Add a new chunk by clicking the Insert Chunk button on the toolbar or by pressing Ctrl+Option+I (Win) or Cmd+Option+I (Mac).

When you save the notebook, an HTML file containing the code and output will be saved alongside it (click the Preview button or press Ctrl+Shift+K (Win) or Cmd+Shift+K (Mac) to preview the HTML file).

---

The preview shows you a rendered HTML copy of the contents of the editor. Consequently, unlike Knit, Preview does not run any R code chunks. Instead, the output of the chunk when it was last run in the editor is displayed.
