sorting factors
...bs. For example, I have a factor called "artic" with three possible values that I would like to order in a specific way -- but I'm not sure how to go about this. > test <- read.table("test.tab",header=TRUE,sep="\t") > artic = factor(artic,levels=c("lowlip","dental","apex")) > test.frame <- as.data.frame(test) > test.xtabs <- xtabs(freq ~ artic + var, test.frame) > mosaicplot(test.xtabs,shade=TRUE) Any help appreciated, Gina
