Boxplot, formula interface, and labels.

Just change the separator:

data(Titanic)
Titanic.df <- as.data.frame(Titanic)
boxplot(Freq~Class*Sex, Titanic.df, cex.axis=.6, sep="\n")

See attached .png.

mybp <- boxplot(count ~ geno * tissue, data = mydata, plot = FALSE) mybp$names <- gsub("\\.", "\n", mybp$names)
bxp(mybp)

See ?boxplot for details.

I have data I'd like to plot using the formula interface to boxplot.
I call boxplot like so:

with(mydata, boxplot(count ~ geno * tissue))

I get a boxplot with x axis labels like "wt.kidney".  I would like to
change the '.' to a newline.  Where is this separator configured?

Thanks,
