Dear R-sters,
I was wondering if anyone has encountered the following issues. I've figured out how to get multiple levelplots [library(lattice)] on a single plot. However, when I add text (adding axis labels for the entire four panel plot) the text is missing when I insert the *.eps file I've created into my LaTeX document (via MikTeX-WinEdt). And, I've just upgraded to R v2.0.1 from v1.8.1 (Windows), and each individual levelplot is smaller compared to the older R release.
Any clues as to 1) how I can recover the lost text, and 2) increase the size of each of the levelplots?
Cheers,
Jeff Jorgensen
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sample code that illustrates what I'm trying to do:
#create a levelplot
x<-seq(pi/4, 5*pi, length = 100)
y<-seq(pi/4, 5*pi, length = 100)
r<-as.vector(sqrt(outer(x^2, y^2, "+")))
grid<-expand.grid(x=x, y=y)
grid$z<-cos(r^2) * exp(-r/(pi^3))
a<-levelplot(z~x*y, grid, cuts = 50, xlab="", ylab=",
colorkey = FALSE)#create the multiple panel plot, here using all the same levelplot trellis.par.set(list(background=list(col="white"))) #white background #using position to scale the plots up and to the right ~10% #to make room for the axis labels print(a,position=c(0.1,0.1,1,1),split=c(1,1,2,2),more=T) print(a,position=c(0.1,0.1,1,1),split=c(1,2,2,2),more=T) print(a,position=c(0.1,0.1,1,1),split=c(2,1,2,2),more=T) print(a,position=c(0.1,0.1,1,1),split=c(2,2,2,2),more=F) #commands that let you click where you want the labels centered ltext(grid::grid.locator(),lab="x-axis label, where I click",cex=1.5) ltext(grid::grid.locator(),lab="y-axis label, where I click",cex=1.5,srt=90) #save device to an *.eps file, to be called later by a \includegraphics command dev.copy2eps(file="twobytwoplot.eps")
