[R] formula version of sunflowerplot() fails when axis label specified

[Gerrit Eichner]

Hello, R-help,

does anybody have already a work-around for the problem that the formula 
version of sunflowerplot() throws an error when provided with a value for 
xlab (or ylab) different from NULL:

> sunflowerplot( Sepal.Length ~ Sepal.Width, data = iris, xlab = "A")
Error in model.frame.default(formula = Sepal.Length ~ Sepal.Width, data = iris,  :
   variable lengths differ (found for '(xlab)')

And are you -- the one with the work-around -- willing to share it? :)

  Best regards  --  Gerrit
