Dear R People:
I'm sure that this is a very silly question, but I'm reading the
Software for Data analysis book by John Chambers, and I can't find the
"Declination" data that he refers to on page 15 in the book.
I did all of the usual stuff:
library(help=SoDA)
??Declination
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.

looked for it online but to no avail.
Has anyone else run into this, please?
Any help would be much appreciated.
Thanks,
