BST 692 Summer 2020 - Assignment 5

You will make a package called someWHAT to document your new function called some. The some function will have a manual page and a vignette to show how it works as well as unit tests.

• Write a function called some() which takes a vector and returns the total (what could be called the sum of the values).
• some() should check to make sure that the user passes data that can be used for a sum.
• If a user does not pass some() valid data it should return easy to understand error messages.

• Write a unit test that checks to make sure that some gives the correct answer
• Write a unit test that checks that all the errors work properly.

• There should be a manual page that explains how to use some.
• There should be a vignette that has a longer explanation of what some does and its errror messages.

We will evaluate the package base on:

• the clarity of the manual, vignette and the error messages
• if it passes all the tests for a CRAN submitssionand
• if it gives the correct answers to our tests
