'Run only R commands in rmd file

I have a large Markdown file (*.Rmd) and want to execute only the R commands in that file (not the text) in RStudio. How can this be done?

If I mark the whole document and try to execute it, R tries to execute also the text in the Markdown file, which, of course, results in errors.
