[R] ggplot2: remove axis ticks

[Brian Smith]

Hi,

I was trying to remove the axis tick marks and their values using theme()
but haven't had much success. Here is sample code:

rx <- sample(1:100,10)
ry <- sample(1:100,10)
rz <- sample(letters[1:3],10,replace=T)
rdf <- data.frame(rx,ry,rz)

p <- ggplot(rdf,aes(x=rx,y=ry))
p1 <- p + geom_point(aes(shape=factor(rz),colour=factor(rz)),size=6) +
    theme(axis.ticks = element_blank(), axis.text.x =
element_blank(),axis.text.y = element_blank()) +
    scale_shape_manual(values=rz)  + theme_bw() +
    labs(colour='rz',shape='rz')
p1
