The current development version (2009-05-11 r48528) contains in ?factor a description of levels parametr levels: an optional vector of the values that 'x' might have taken. The default is the unique set of values taken by 'character(x)', sorted into increasing order _of 'x'_. Note that this set can be smaller than 'sort(unique(x))'. I think that 'character(x)' should be 'as.character(x)'. Petr. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
