Review of “R For Dummies”

The authors are Andrie de Vries and Joris Meys.

Executive summary

Pretty much all I’d hoped for — and I had high hopes.


The “Dummies” series is popular for introducing specific topics in an inviting way. R For Dummies is a worthy addition to the pack.

There is a competitor by the name of Statistical Analysis with Excel For Dummies.  Now this may also be well-executed — it probably is — but some of us are of the opinion that the last two words of the title are redundant.

There are millions of people doing data analysis in spreadsheets, even though spreadsheets are dangerousR For Dummies gives these people a reasonable entrance into the world of R where their analyses will be safer, faster and deeper — after an admittedly uncomfortable period of adjustment.

The world will be more productive on account of people switching from spreadsheets to R for data analysis.  The problem is that hardly any spreadsheet users are aware that there is a more comfortable way of living than walking along a cliff edge.  The cliff is invisible to them.  Hopefully R For Dummies will help change that by making R a more obvious alternative.


Chapter 19 is “Ten Things You Can Do in R That You Would’ve Done in Microsoft Excel”.  They resisted the subtitle “And by the way, generally much easier too”.

Writing introductions to computer programs is astoundingly hard.  A key problem is the curse of knowledge.  Once we know something, we find it hard to imagine not knowing.  So a writer who knows the program is not good, but a writer who doesn’t know the program is no use as a navigator.  R For Dummies sails these stormy seas well, partly from the discipline of the “Dummies” template, partly from the skill of the authors.  They are competent in R yet both relatively new converts.

The really important decisions when writing introductory documentation is what not to say.  I think Andrie and Joris made very good selections for silence.

… you discover the power hidden behind the 18th letter of the alphabet.


There are (at least) two major styles of learning.  There are those (like me) who are perfectly happy to gather up detail after detail, and only eventually put the details into a big picture.  There are others who need to see the big picture before they can pick up any details (and possibly revise the picture).

R For Dummies is probably closer to what the big-picture people need than any other R documentation I know, but I doubt it really fulfills the need.  However, that is probably too much to ask.  I think a separate (short) document is called for.

If you’re a big-picture learner, I’d be interested to hear what you think should go into such a document.

Cool things I didn’t know


For Windows there is the writeClipboard function.  Give it a character vector as an argument and those are put onto the clipboard:

> writeClipboard(head(letters)) 
# hit <return> then <control>v
> a
Error: object 'a' not found
> b
Error: object 'b' not found
> c
function (..., recursive = FALSE)  .Primitive("c")
> d
Error: object 'd' not found
> e
Error: object 'e' not found
> f
Error: object 'f' not found

Of course the function is better used by pasting into other programs rather than pasting back into R.

multiple sorting

If you are using order to sort based on multiple items and you want some in increasing order and some decreasing, then there is the xtfrm function to help you.


There is a companion post “Annotations for R For Dummies that has a number of specific comments on the book.
