c()ombine
Now is where things get fun! It is time to create your first vector. Since this is a finance oriented course, it is only appropriate that your first vector be a numeric vector of stock prices. Remember, you create a vector using the combine function, c(), and each element you add is separated by a comma.
For example, this is a vector of Apple's stock prices from December, 2016:
apple_stock <- c(109.49, 109.90, 109.11, 109.95, 111.03, 112.12)
And this is a character vector of bond credit ratings:
credit_rating <- c("AAA", "AA", "BBB", "BB", "B")
This is a part of the course

- Another example of a numeric vector for IBM stock prices is shown for you.
- Create a character vector of the
