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(): for example, deps(file_store("report.md")). 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.

file_store(x)

Arguments

x

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

Value

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

Examples

# Wraps the string in single quotes. file_store("my_file.rds") # "'my_file.rds'"
#> [1] "\"my_file.rds\""
