Tricks beyond basic usage in README
Show a multi-line expression example
reprex({ x <- 1:4 y <- 2:5 x + y })
and point out one can then "select all" + RStudio Run button or keyboard shortcut. Or, with cursor in reprex-containing source editor, RStudio Source button or keyboard shortcut.
Remind people you can use all your usual knitr::spin
tricks, like create headings, insert regular prose, and set chunk options. Put this code on the clipboard and the reprex()
it. (Hey, our expression parsing doesn't handle this but probably should...)
#' ## Hey I'm a heading x <- 1:4 #' blah blah #+ eval = FALSE y <- 2:5 x + y
Add the following code to your website.
