In accordance to the instructions on how to develop packages available under http://r-pkgs.had.co.nz/ and the
devtools package, I put the R source files of my package in the folder
If I need to call a function from another file in a particular file, then I need to call
source("file_with_function.R") in this file.
After the package has been build (
R CMD build my_package), then the call to
source("file_with_function.R") is as far as I know no longer necessary.
Can I avoid the
source() calls during development without getting error messages that objects/functions in other files don't exist?
