Read this if one of the following applies to you:

• You are using library(package) or require(package) inside your functions
• You don't know exactly when you need the syntax package::function() or package:::function() as opposed to function().

If you are using functions from other packages inside functions of your own package, then you are dealing with NAMESPACE issues. NAMESPACE is one of the most confusing parts of an R package. Prepare for your brain to hurt a bit. This information will not answer all your questions, but it will rise an alarm that may save you time and trouble.

From http://r-pkgs.had.co.nz/namespace.html, find section "Imports" and read its introduction and also the subheading "R functions".

R functions

maurolepore

• Add dplyr and tidyr to DESCRIPTION.
• Refer to functions as dplyr::FUNCTION() and tidyr::FUNCTION().
• Remove all !! and := because in this case you don't need them.
• Add new_df at the end so that it is returned.
• Rebuild, reload, rerun myfunction.

• Don't hard code settings (e.g. figure colours), read them from a file via read_settings().

The code is more readable and flexible than it would be if a value were hard-coded. You don't need to change the program to change titleBar.color ; you simply change the contents of the source that's read by"

-― from "Code Complete (Developer Best Practices)" by Steve McConnell, http://a.co/b75gLyw

• Prefer long informative names over short uninformative ones (8-20 characters is ok)

In modern languages like C++, Java, and Visual Basic, you can create names of virtually any length; you have almost no reason to shorten meaningful names.
