Tackling knitting errors in R Markdown

When knitting an R Markdown document after the first time, errors may sometimes appear. Three tips are recommended below.

1. Close PDF reader window

When the document is knitted through the ‘Knit’ button, a PDF reader window opens to present the result. Closing this window can help resolve errors.

2. Delete service files

Every time the Rmd is knitted, some service files are created. Some of these files have the ‘.tex’ extension (e.g., index.tex, Appendix-B.tex), whereas others do not (e.g., index.log, ZHJhZnQtYXBhLlJtZA==.Rmd, index.synctex.gz). Deleting these files can help resolve errors (see a possible function).
