Bjoern, thanks for your mail. But when reporting problems with a contributed package, please contact the maintainer first or at least Cc him when writing to R-help.
The problem below is in the formula method of sigest because the frac argument gets passed on to model.frame which causes the error. I'll commit a fix, but you can do it also easily locally if you add the second line of m$scaled <- NULL m$frac <- NULL in the formula method of sigest.
