As of this writing, there are more than 3000 objects in the R base packages, and more than 15,000 other packages available on CRAN, most containing dozens of objects of their own. This represents a huge amount of functionality, and nobody could be expected to remember it all. The best we can hope for is that people should be able to discover it, using the help system and other resources, as well as judicious guesses about where to look. Guessing is made easier when consistent principles are followed as code is written. For example, names should reflect the purpose of packages and functions. Guessing is made harder by inconsistency, for example when names are poorly chosen, or conventions for forming names are inconsistent.
