# Avoiding (R) Markdown knitting errors using knit_deleting_service_files()

The function knit_deleting_service_files() helps avoid (R) Markdown knitting errors caused by files and folders remaining from previous knittings (e.g., manuscript.tex, ZHJhZnQtYXBhLlJtZA==.Rmd, manuscript.synctex.gz). The only obligatory argument for this function is the name of a .Rmd or .md file. The optional argument is a path to a directory containing this file.

The function first offers deleting potential service files and folders, for which the user’s approval is requested in the console (see screenshot below). Next, the document is knitted. Last, the function offers deleting potential service files and folders again.

NOTE: The deletions, if accepted, are irreversible as they are made through unlink(). Therefore, our familiar adage truly applies: this function comes with ABSOLUTELY NO WARRANTY. Please ensure you understand the source code before using the function.

After doing a research master's, I became a PhD student and graduate teaching assistant in Psychology at Lancaster University, where I investigated how conceptual processing—that is, the comprehension of the meaning of words—is supported by linguistic and sensorimotor brain systems, and how research on this topic is influenced by methodological aspects such as the operationalisation of variables and the sample size of experiments. Currently, I am a postdoctoral fellow at UiT The Arctic University of Norway, where I am investigating the behavioural and neural underpinnings of multilingualism. Throughout my research, I have used methods such as behavioural and electroencephalographic experiments, corpus analysis, statistics and programming. My CV is available at https://osf.io/84ktq.
