Knitting with errors

[Caroline-Seip]

For anyone who's had problems knitting their RMarkdown files with intentional errors, you can either put {r error=TRUE} at the top of the code chunk you want to accept an error in, or

To accept errors throughout the entire document put
{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE, error = TRUE)

As a code chunk at the top of the file. This code chunk automatically comes up when you make a new RMarkdown file, just need to add the error=TRUE part

Shoutout to @ChadFibke and @j-schaub for helping me out with this one

You can also use the try() function. Here's sample code:

res <- try(log("hi"))
if (inherits(res, "try-error")){
     print("res resulted in an error!")
}
