I downloaded SoDA and did a search of the package directory. There is  
code referring to the Declination column of a mars dataframe. Trying:

require(SoDA)
## requires mars data.frame
SoDA:::.getMarsData()

# I get an error

Then I see in the package docs:
"Details
Note that not all the examples shown in the book correspond to an  
explicit example file. Also, some
of the data sets used are not explicitly open-source and so are not  
included in this package. For
example, the mars data exists on the web as an Excel file; you need to  
export that as a ".csv"
file to run the corresponding examples. "

Presumably you need to follow directions that are not in the package  
docs but must be in the book.
