I have an issue when making a wireframe plot. I can't find any way to
change the number of ticks on the labels. I try to set it in the code
below with z.ticks=1, but that doesn't work. Is there anything that
works? (Note. I need to use wireframe. persp is out of the question
since I want mathematics in the axis labels).
Here is some sample code:
library(lattice)
x <- as.matrix(seq(0,pi,0.1))
z <- sin(x) %*% t(sin(x))
dim(z) <- NULL
xy <- expand.grid(x,x)
w <- data.frame(xy[,1],z,xy[,2])
colnames(w) <- c('x','z','y')
wireframe(z~x*y, data = w,
xlab = expression(italic(x)),
ylab = expression(italic(y)),
zlab = expression(sin(italic(x*y))),
screen = list(z=25,x=-60),
scales = list(z.ticks=1, arrows=FALSE))
I'm thankful for any help!
Best regards,
Fredrik Johansson
