"mtcars" should be replaced by "mpg"

Page 11 last paragraph, line 5 .
It is: " the solid shapes (15-18) are filled with color."
It should be: "the solid shapes (15-20) are filled with color."

Plots on Page 16 are not the intended graphs.
Left plot should be a scatter plot
Right plot should be the one printed in the left hand position.

Plots are not output from code in last paragraph:

... to make the preceding plots, you can use this code:

# left
ggplot(data = mpg) +
geom_point(mapping = aes(x = displ, y = hwy))

# right
ggplot(data = mpg) +
geom_smooth(mapping = aes(x = displ, y = hwy))

2 possible corrections :

1) change plots: on line version on http://r4ds.had.co.nz/data-visualisation.html 3.6 shows correct plots

2) change code :

# left
ggplot(data = mpg) +
geom_smooth(mapping = aes(x = displ, y = hwy))

# right
ggplot(data = mpg) +
geom_smooth(mapping = aes(x = displ, y = hwy, linetype = drv))

On p. 16, under the title of Geometric Objects, there are two plots. At the bottom of the page are two lines of R code to describe/create them. The R code marked # left does not generate the graph on the left. The R code (the second line) marked # right generates that first graph. The graph on the right looks like it's the same as the graph on the next page. The first graph should look like the graph on p. 5.

The graphic under Geometric Objects section is wrong in the printed version (1st edition, 2nd release)

In the fourth release, the code labeled "right" produces the graph on the left and the code labeled "left" produces the graph on page 5. The right figure on page 16 is produced by the code on page 17.

Using "fun.ymin", "fun.ymax" and "fun.y" succeeds, but returns an error message that they are deprecated.

The two plots showing the use of position = "identity" are missing.

The 7 Venn diagram graphics in the "Logical Operators" paragraph are not shaded at all, so they all look identical. They are all supposed to have unique shadings to indicate the 7 different Boolean operations.

This book is great, you guys did a fantastic job from what i can see so far, keep up the good work!!!

The code
filter(flights, month == 11 | 12)

doesn't find all flights in January, but all flights in the year!

equality operator == has higher precedence than or operator |
you must read (month==1) | 12 not month == (11|12)

With ggplot2 version 3.2.1, an additional legend is produced for geom_smooth() relating to the alpha value (= 1/3 in the text). This legend was not shown on the glyph, but was produced following the code fragment just above the glyph on the PDF version. To shut this extraneous legend off, add the line "+ scale_alpha(guide = FALSE)" within the ggplot call. This is more of a note than a mistake.

The graphic under "Graphics in Two Categorical Variables" section is wrong in the printed version (1st edition, 2nd release).
It is repeating the previous graphic.

The online version is correct

The text uses the "parse_number()" function from the "readr" package. But the actual function name is (now) "parse_numeric".

The third example of "parse_number()" (which should be parse_numeric()) shows a final result of 123. The correct result is 123.45.

The years are repeated on the x-axis, with 1999 appearing twice and 2000 appearing three times. This behavior no longer appears as of dplyr 0.7.2 and ggplot2 2.2.1, but even now the default x-axis labeling could be improved by treating year as a factor or by explicitly labeling 1999 and 2000 on the x-axis.

The shading in the book is virtually non-existent, so it's impossible to see the results of str_view() on the printed pages.

phone <- regex(

6th hash mark has code for last three numbers
but last section in the phone number is four numbers

code should read:

(\\d{4}) #four more numbers

for sigma<- and mu<- objects, text uses "n = 5" but the graphic illustrating the idea uses "n = 10".

the graphic refers to an object called "params" but the object is called "param" in the text. On page 335 there is a similar problem. "Params" is used but I think they mean "param." It may not matter in this case.

In the book, the code for creating the plot is this one:

ggplot(mpg, aes(displ, hwy)) +
geom_point(aes(color = class)) +
geom_smooth(se = FALSE) +
labs(
title = paste(
"Fuel efficiency generally decreases with"
"engine size"
)

This code generates an error, the correct code is this:

ggplot(mpg, aes(displ, hwy)) +
geom_point(aes(color = class)) +
geom_smooth(se = FALSE) +
labs(
title = paste(
"Fuel efficiency generally decreases with",
"engine size"
)
)

Minor error in the code for the plot:

ORIGINAL:
ggplot(mpg, aes(displ, hwy)) +
geom_point(aes(color = class)) +
geom_smooth(se = FALSE) +
labs(
title = paste(
"Fuel efficiency generally decreases with"
"engine size",
)
subtitle = paste(
"Two seaters (sports cars) are an exception"
"because of their light weight",
)
caption = "Data from fueleconomy.gov"
)

CORRECT:
ggplot(mpg, aes(displ, hwy)) +
geom_point(aes(color = class)) +
geom_smooth(se = FALSE) +
labs(
title = paste(
"Fuel efficiency generally decreases with",
"engine size"
),
subtitle = paste(
"Two seaters (sports cars) are an exception",
"because of their light weight"
),
caption = "Data from fueleconomy.gov"
)

the command
?rmarkdown:html_document() should use double colons :: like

?rmarkdown::html_document()

(550 is the position on my Kindle)


# left
ggplot(data = mpg) +
geom_point(mapping = aes(x = displ, y = hwy))

should be changed to: geom_smooth
