> **Dilsher Singh Dhillon** (@dhillon_stats; 3/0): @Ben_D_Douglas @rstats4ds You can write warning = FALSE, message = FALSE in whatever chunk you don't want the warnings and messages to appear. If you wanted to do this for the whole document, you can do something like knitr$opts(warning = FALSE, message = FALSE) in your first chunk.

> **Will Landau** (@wmlandau; 1/1): Does anyone know how to supply language objects to chunk options in #knitr/#rmarkdown?

> **Dale Maschette 🐟🧗‍♂️** (@Dale_Masch; 1/0): @AmyStringer11 So - I have discovered you can pull out pieces of code using knitr::read_chunk() but it relies on you putting a label tag ## ---- in the chunk you cant use the rmd chunk label as far as I can tell.

> **Will Landau** (@wmlandau; 1/0): @jaredlander @gshotwell @chrisderv @grrrck @iflores_siaca @PeeltothePithy @chrisderv, is it normal / good practice for a package to assign {knitr} engines in .onLoad()? I think it would be super convenient for users if you could just call library(targets) in a report and have the chunk engines immediately available.
