Dear Detlew,

» Don't worry. Many R users are fallen or will fall into this trap I think, amongst others me.

Count me in.

» » Shall we add a line to PowerTOST’s functions as a precaution?
» »   if (is.factor(design)) design <- as.character(design)
» Not a bad idea. But don't really know if this is absolutely necessary and if it pays the effort.

It’s easy for us. But you’re right: Duno how many times a user would set up a data.frame and call the design-argument in a loop.
