11.2 Do not stop on error
Sometimes you may want to show errors on purpose (e.g., in an R tutorial). By default, errors in the code chunks of an Rmd document will halt R. If you want to show the errors without stopping R, you may use the chunk option
error = TRUE, e.g.,
You will see the error message in the output document after you compile the Rmd document:
Error in 1 + "a": non-numeric argument to binary operator
In R Markdown,
error = FALSE is the default, which means R should stop on error when running the code chunks.
