R devel - Dec 2001 - boxplot labels incorrect when horizontal = TRUE (PR#1207)

#Example:

y <- rnorm(10)
group <- gl(2,5)

plot(y ~ group, horizontal = TRUE)  # BUG: default xlab & ylab interchanged
plot(y ~ group, horizontal = FALSE) # OK: supplies correct default xlab &
ylab


# Using boxplot() instead of plot() omits default axis labels altogether
# (not sure if this is intentional):

boxplot(y ~ group, horizontal = FALSE) # no default axis labels supplied
boxplot(y ~ group, horizontal = TRUE)  # no default axis labels supplied

Thank you!

Um.  That's plot.formula, not boxplot.  horizontal = TRUE is *not* a
documented argument to plot.formula.  If you pass arguments to boxplot
through ... (rather than just par values), you may well get unexpected
results.

To fix this needs plot.formula to recognize horizontal, and that's
an API change which I don't advocate during feature freeze.
Generally, not doing something which is not documented to happen is not a
bug, so I'll put this on the wishlist.

Yes, it's intentional.  You can always use title().
