count_package_lines: Count the lines of all functions in a loaded package
In DavidBarke/QWUtils: Useful Methods For Programming with Shiny

Count the lines of all functions in a loaded package, which is NOT equal to the number of lines of the scripts defining the functions due to the absence of the roxygen documentation. Furthermore only functions are considered and not for example R6 objects.

1	count_package_lines(package, output = c("sum", "separated"))

`package`	Package name.
`Output`	If `"sum"`, calculate the sum of all lines; if `"separated"`, show number of lines for each individual package function.
