cenbox(): Changing Default x-axis Group Labels

[Rich Shepard]

   I've looked at the lattice book and the 'R Graphics Cookbook' without
seeing how to change the labels along the x axis for groups in a box plot,
specifically cenbox().

   The attached example has a main and axes labels with default group labels.
Please point me to a reference on how I can change 'FALSE' and 'TRUE' to
something more easily understood by viewers.

TIA,

Rich

Hi Rich,

I don't have a cenbox() function that I can find, but your solution will
(probably? hopefully?) be along the lines of:


foo <- boxplot( y ~ x, data=sdf, plot=FALSE)

foo$names <- ifelse(foo$names, "Label for TRUE", "Label for FALSE")

bxp(foo)


where sdf is a dataframe containing your data and y and x are appropriate
variables in it.

Don,

   Well, I must have mis-typed that although I'm sure I read about it in the
NADA.pdf or Dennis' book. I'll look again. I don't get an error when calling
this method. Will look further and provide more information.

   I will definitely work more on this. Right now I need to get my client to
explain the many discrepancies in the data they sent before I go further
with analyses.

Thanks very much,

Rich

Well, You didn't say (in your original request) that you were using
the NADA package. The function is cenboxplot() and it's just a
wrapper for boxplot() and hence passes arguments to boxplot().
Thus the solution to your problem is just to add the 'names='
argument, as in (using the example in ?cenboxplot):

   with(Golden, cenboxplot(Blood, BloodCen, DosageGroup,
                names = c("yabba", "doo")))

p.s. I can sympathize with your client data troubles. 'Tis ever thus.

Peter,

   Thank you. I wrote off the top of my head and obviously missed the correct
function name.

> p.s. I can sympathize with your client data troubles. 'Tis ever thus.

   Yep. They all use spreadsheets rather than databases and there's no
integrity checks. Sigh. Well, the pay's the same regardless.

Carpe weekend,

Rich
