Dear R-help.
When plotting 3D wireframe plots with the lattice package, there is often
a lot of space between the actual plot (i.e., cube) and panel borders. For
a single wireframe, this is not a problem, but when plotting multiple
wireframes, the wasted space decreases the size of the plots very much.
Is there a way to decrease this space/margin? I could not find any
information about it in the documentation.
Here is example code for two panels showing the problem.
library(MASS)
library(lattice)
n = 10^3
x1 = rnorm(n)
y1 = 3 * x1 + 5 * rnorm(n)
x2 = rnorm(n)
y2 = 3 * rnorm(n) + 5 * rnorm(n)
ran = c(range(c(x1, x2)), range(c(y1, y2)))
xy1 = con2tr(kde2d(x1, y1, n = 30, lims = ran))
xy1$dist = "correlated"
xy2 = con2tr(kde2d(x2, y2, n = 30, lims = ran))
xy2$dist = "uncorrelated"
xy = rbind(xy1, xy2)
wireframe(z ~ x * y | dist, xy, screen = list(z = 16, y = -5, x = -47))
