[R] Remove the border/frame in a dotplot()

[stéphanie braun]

Dear listmembersI wouldlike to remove in a dotplot() the border/frame from the figure and only keepthe x- and y-axis. I can’t find a way to do this. bty="n" does notwork. Can somebody help? I include the r coding for my figure below. dotplot(plant_species ~ mean, data =botany,            aspect= 1.5,            scales=list(x=list(tck=c(-1,0)),y = list(tck=c(-1,0))),            ylab= "Plant species",            xlim= c(-1.1, 1.1),            xlab= "Electivity index",prepanel = NULL,            panel= function (x, y) {            panel.abline(v=0)            panel.xyplot(x,y, pch = 16, col = "black")            panel.segments(botany$lower,as.numeric(y),            botany$upper,as.numeric(y), lty = 1, col = "black")}
