I'm getting an error when using strwidth after a lattice graphic is drawn:
library(lattice) xyplot(runif(20) ~ runif(20)) strwidth('xxx')
Error in strwidth("xxx") : invalid graphics state
Any help appreciated. I have version 2.0.1 of grid and version 0.10-14 of lattice.
The advice is `don't do that'!
strwidth() is a base graphics command, and will only work if a device is currently plotting base graphics. Lattice is built on grid, which has
stringWidth().
... and convertWidth() is useful to display stuff afterwards in an interpretable way ...

Thanks Uwe and Brian. Before the latest versions, grid would let me use ordinary graphics functions to deal with the currently rendered plot after I did par(usr=c(0,1,0,1)), so I was lazy. I changed my code to use specific grid functions.
