[R] lattice: axis ticks, axis alignment and remove axis from plot

[Katharina May]

Hi there,

I'm a bit confused concerning the axis tck setting in the lattice
package as the ticks on left sided axis aren't
drawn at all with the following setting:

dados <- data.frame(varsep = factor(rep(1:2,10)),
                    i = runif(20))

library(lattice)

my.theme <- list(
        axis.components = list(left = list(tck = 1, pad1 = 1, pad2 =
2), top = list(tck = 0, pad1 = 1, pad2 = 0), right = list(tck = 0,
pad1 = 1, pad2 = 0), bottom = list(tck = +0.5, pad1 = 1, pad2 = 2)))

trellis.par.set(theme = my.theme)


bwplot(varsep ~ i, dados,
       xlab = names(dados)[1],
       ylab = names(dados)[2],
       panel = function(...) {
       	 panel.grid(v = -1, h = 0)
       	 panel.bwplot(...)
       })
	


Maybe somebody can help me recognise the problem why the left sided
ticks are not drawn.

I'm also wondering how to tell the trellis object not to draw the
right and top axes at all an how to align the y axis
that it goes through x=0?

Thanks,

        Katharina
