When I open a new RMarkdown file in RStudio, the YAML header in the default html option conveniently has the date of the file's creation already filled in. For instance:
--- title: "Default HTML output" author: "Me" date: "6/19/2018" output: html_document ---
I would like to incorporate this auto-fill feature into custom html templates in my R pacakge. However I can only find guidance on printing the current date in the knitted report, whereas I want the date auto-filled into the RMarkdown YAML header.
--- title: "" author: "Me" date: '`r format(Sys.Date(), "%Y-%B-%d")`' output: html_document ---
How can I enable the date to be auto-filled into the custom template, just like in the default html option?
