Hi
This might work, though it's a teensy bit more complicated and a bit
manual (on the left axis labels) and it ignores heights and vertical
whitespace ...
library(lattice)
d <- dim(volcano)
xy <- data.frame(x = 1:d[1], y = volcano[,30] )
library(grid)
grid.newpage()
pushViewport(viewport(y=0, height=.5, just="bottom"))
# Force identical widths where we can
layout.widths <- lattice.options("layout.widths")[[1]]
layout.widths$ylab <- list(x=1, units="cm", data=NULL)
layout.widths$panel <- list(x=1, units="null", data=NULL)
layout.widths$key.right <- list(x=1, units="cm", data=NULL)
lattice.options(layout.widths=layout.widths)
# Force (width of) left axis labels to be the same
vol_p <- levelplot(volcano, scales=list(y=list(at=seq(10, 60, 10),
labels=rep(" ", 6))))
print(vol_p, newpage=FALSE, prefix="vol_p")
downViewport("vol_p.panel.1.1.off.vp")
# Draw proper left axis labels
grid.text(seq(10, 60, 10), x=unit(0, "npc") - unit(1, "lines"),
y=unit(seq(10, 60, 10), "native"), just="right",
gp=gpar(cex=.8))
# Determine width of levelplot panel
border <- grid.get("border", grep=TRUE)
width <- convertWidth(border$width, "in", valueOnly=TRUE)
xscale <- current.viewport()$xscale
upViewport(0)
pushViewport(viewport(y=.5, height=.5, just="bottom"))
# Force identical widths where we can
layout.widths$ylab <- list(x=1, units="cm", data=NULL)
layout.widths$panel <- list(x=width, units="in", data=NULL)
layout.widths$key.right <- list(x=1, units="cm", data=NULL)
lattice.options(layout.widths=layout.widths)
# Force (width of) left axis labels to be the same
xy_p <- xyplot(y ~ x, data = xy, xlim=xscale,
scales=list(y=list(at=seq(100, 200, 20),
labels=rep(" ", 11))))
print(xy_p, newpage=FALSE, prefix="xy_p")
downViewport("xy_p.panel.1.1.off.vp")
# Draw proper left axis labels
grid.text(seq(100, 200, 20), x=unit(0, "npc") - unit(1, "lines"),
y=unit(seq(100, 200, 20), "native"), just="right",
gp=gpar(cex=.8))
upViewport(0)
