Errata

The output of the data frame has seven columns. The last column was created in the code and called "pos". However the header for that column is missing in the output sample. So "pos" should appear directly above "FALSE" in the table.

This was correct syntax in an old version of R but the following is not true in current versions of R:

"A beautiful aspect of mean and sd is that they are smart about data frames."

To get sum of rows or columns you must use rowsum or colsum.

I wish there would be a revised edition to correct such issues. I'll bet there are more.

Solution (i.e., > scores <- edit(score) # Invoke editor, overwrite with edited data) should read edit(scores) rather than "edit(score)" in order to produce a result in R.

wrong : third columns
correct : fourth columns

wrong : > suburbs[c(1,3)]
correct : > suburbs[c(1,4)]

You have:

f <- factor(c("A","C","C","B","C"))

But in the diagram that follows, you write the factor as:

A
C
A
B
C

So, you need to make this change:


f <- factor(c("A","C","A","B","C"))

'spearman' should not be capitalized in method. Same problem on p 216, 4th paragraph

The second code example mentions "suppressuWarnings()" function instead of "suppressWarnings()".
The middle "u" is a typo.

Page 330, at the top, incorrectly lists the suppressMessages() function as
suppressMessage(). You left out the "s".

This is in the index. The line says:
if statements, 48
But there is no mention about if statements in this page. Also, in page 413 we have:
while statements, 48
Again we have no mention of while statements in that page.
Furthermore, flow control statements were completely forgotten in this book. They surely deserved at least a mention.

The test reads:

Use the prop.test function. Suppose the sample
size is n and the sample contains
x successes:

> prop.test(n, x)

It should read as:

> prop.test(x, n)
