I can put fun1 and fun2 in separate .R files and add abit of #' but am unsure to include all relevant requirements for roxygen and also am unsure what to include as relevant requiremetns and how to use it to create the rd documentation to go with a package are. This chapter discusses .Rd files and the collate field. Use the Rdocumentation package for easy access inside RStudio.
