[R] mosaic plot of vcd package does not stretch with 2-dimension?
Hi, I like mosaic function of vcd package. I have played around it. I have found out that mosaic plot data table is 2-dimension does not stretch when you enlarge a mosaic plot. It is okay when data table is 3 or more dimension. The first one is of 3-dimension table case, and the second one is 2-dimension. With the first plot, you can drag window to enlarge a plot. With the second, I cannot. I have gone through the document, but I could not find any specific to solve this problem. Thank you, Sang Chul === music = c(210, 194, 170, 110, 190, 406, 730, 290) dim(music) = c(2, 2, 2) dimnames(music) = list(Age = c(Old, Young), Education = c(High, Low), Listen = c(Yes, No)) mosaic(music) === === music = c(210, 194, 170, 110, 190, 406, 730, 290) dim(music) = c(2, 4) dimnames(music) = list(Age = c(Old, Young), Education = c(High, Low, Upper, Lower)) mosaic(music) __ 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.

You need to set keep_aspect_ratio = FALSE This is described on the man page for strucplot() (which is the workhorse function behind mosaic()): 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. hth, Z I have gone through the document, but I could not find any specific to solve this problem.
