Re: [R] Manipulating x axis in stripchart

If its ok to use lattice try this: library(lattice) # no attach needed # we want VC to be first level, not OJ ToothGrowth$supp <- relevel(ToothGrowth$supp, "VC") # rename levels levels(ToothGrowth$supp) <- c("A", "B") # plot dotplot(len ~ supp | dose, ToothGrowth, layout = c(3, 1)) On Nov 20

[R] Manipulating x axis in stripchart

Hi all, I I need to manipulate the x axis in a stripchart. I will use one of the data sets included in R to explain what I need to do. attach(ToothGrowth) stripchart(len[supp=='VC']~dose[supp=='VC'], vertical=TRUE, group.names=c('A','A','A')) stripchart(len[supp=='OJ']~dose[supp=='OJ'], add=
