Update tidy.Rmd (#865) 
Line 506: 
When fixing the string format in the `key` column using the `str_replace` function, I think the column name was mistakenly stated as "names_from", where it should actually be "key", which is the original column name.

one_of() is retired (#867) 
Further to {tidyselect} documentation "one_of() is retired in favour of the more precise any_of() and all_of() selectors." this exercise (5.4.1) should be updated to be in-line with current functionality.

Jeffrey Arnold 5f85b4c592 Remove use of mu in exercises (#748) 
Two exercises use $\mu$ to mean the mean parameter of a normal distribution. However, nowhere in the book is it defined as such. For clarity replace $\mu$ with "mean".

Jeffrey Arnold 5082dd8bfd Add equations to 19.2 Ex 4. (#749) 
The question asks:

> Follow <http://nicercode.github.io/intro/writing-functions.html> to write your own functions to compute the variance and skew of a numeric vector.

However, the math on that page no longer renders.

Directly include the skew and variance equations in the question.

Bianca Peterson 2712ba113f Fixed text to correspond with code output (#784) 
My guess is that the guess_parser() function was changed/updated since the writing of this book. From '?guess_parser', the following default is used: 'guess_integer = FALSE'. Thus column 'x' is not problematic anymore.

* Fix a few minor typos

Examples include saying we'll learn about filter() in the next chapter, but it's not until chapter 5.  And, also, it says we'll learn about how to use multiple geoms in the same plot in the next section, but then not far below, in the same section, it shows how to use multiple geoms.

* Three minor fixes in chapter 5

* Remove " I introduced in prior commit
