How to source R Markdown file like `source(‘myfile.r’)`?

by

It seems you are looking for a one-liner. How about putting this in your .Rprofile?

ksource <- function(x, ...) {
  library(knitr)
  source(purl(x, output = tempfile()), ...)
}

However, I do not understand why you want to source() the code in the Rmd file itself. I mean knit() will run all the code in this document, and if you extract the code and run it in a chunk, all the code will be run twice when you knit() this document (you run yourself inside yourself). The two tasks should be separate.

If you really want to run all the code, RStudio has made this fairly easy: Ctrl + Shift + R. It basically calls purl() and source() behind the scene.
