STA237 Course Notes

This is an R Markdown Notebook. When you execute code within the notebook, the results appear beneath the code.

Useful R functions

• seq(from = , to = , [by = ], [length.out = ]) - for regularly spaced numeric vectors, where by and length.out are optional parameters for specifying increment size or output size respectively

seq(from = 0, to = 5, length.out = 10)

• use : for range with increment 1

c <- [1:5]
c

plot(cars)

Add a new chunk by clicking the Insert Chunk button on the toolbar or by pressing Ctrl+Alt+I.

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 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.
