Minor error - the "Miscellaneous" Pane is listed as being in the Bottom Left, but it is in the Bottom Right.

I was reading the book A Sufficient Introduction to R and in section 6.3 there is a sentence

We notice that after reading in the data, there is an additional column that just has missing data (the NA stands for not available which means that the data is missing) and a row with just a single blank.

but actually there are 2 columns and 3 rows in data.4 object . I think the sentence above refers to the excel file. Did I misunderstand?
I'm confused and i find that in your another book STA 444/5 - Introductory Data Science using R the description is the same.
In example4.xls, if i use search to search space and choose just match cells i will get the only $4$N
But if i use F5 to locate blank cells, i will get non-blank $j$35 $1$N $4$N.i find $j$35 has 3 spaces.
Do $1$N cell in Excel have any other characteristics or features?
