Three Useful Functions in Base R: regexec(), strrep(), and append()

I just finished reviewing a pull request in the knitr repo that tries to improve the error message when it fails to parse YAML, and I feel three base R functions are worth mentioning to more R users. …

So cool! 😸 I learnt about strrep() recently (it was on my sticky note, you beat me to it 😁) by reading r-lib/lintr#884 (it's in lintr now r-lib/lintr#1652)

Cool! I like this one: x = c("Failed to parse YAML: ", x, "\n", append(meta, cursor, row))

BTW, I can help on the stuffs if still needed

Thank you! Please feel free to work on anything in the list, although I haven't updated this TODO list for a long time, and there are some other things that I'm interested in getting done.

Understood. Please feel free to send me a more recent version or other tasks that you're interested in getting done.
