Not really: note that the images resizes correctly, it just keeps its square aspect-ratio. vcd is so strongly modularized that it can be difficult to find the information required. Check strucplot, where it says: strucplot keep_aspect_ratio logical indicating whether the aspect ratio should be fixed or not. If unspecified, the default is TRUE for two-dimensional tables and FALSE otherwise. So try mosaic(music, keep_aspect_ratio=FALSE) but think over if that's really what you want. In most cases it makes sense to keep the square aspect for 2x2 cases Dieter ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
