stripchart ignores the main title option. For example, in the documentation 

     stripchart(decrease ~ treatment,
         main = "stripchart(OrchardSprays)", 
         vertical = TRUE, log = "y", data = OrchardSprays)


does not yield a plot with "stripchart(OrchardSprays)" at the top of the plot.
Looking at the source code of stripchart.default there is:

....
title(xlab = xlab, ylab = ylab)
....

I would have thought the main would have got wrapped up in the ... that is sent
to the plot command, but then I don't know enough about it.
