This function simply wraps literal double quotes around the argument x so drake knows it is the name of a file. Use when you are calling functions like deps_code(): for example, deps_code(file_store("")). See the examples for details. Internally, drake wraps the names of file targets/imports inside literal double quotes to avoid confusion between files and generic R objects.




Character string to be turned into a filename understandable by drake (i.e., a string with literal single quotes on both ends).


A single-quoted character string: i.e., a filename understandable by drake.
