This poses a challenge when the results are to be presented using R Markdown. One has to walk the line between reproducibility and efficiency. On the one hand, it is desirable to keep the R Ma...

Avoiding knitting errors in (R) Markdown using knit-deleting-service-files()
The function knit-deleting-service-files() is designed to avoid (R) Markdown knitting errors caused by service files from previous knittings (e.g., manuscript.tex, ZHJhZnQtYXBhLlJtZA==.Rmd, manuscript.synctex.gz). The function first suggests deleting potential service files in the directory. A response from the user is required in the console. Ne...
