YAML current date in rmarkdown?

Question

I'm wondering if there's a trick to put the current date in the YAML front-matter of a `.rmd` document to be processed by `knitr` and the `rmarkdown` package. I would like to take advantage of the advanced pandoc wrapper provided by `rmarkdown`, but having R code in the YAML header doesn't seem to work.

Answer 1

date: "`r format(Sys.time(), '%d %B, %Y')`"
