Your LyX example has two problems: 1) We don't have your .RData; 2) You didn't library(reshape) and library(lattice). Hence it is not a self-contained reproducible example.
Yihui, I assumed that reading in the *.csv file would create a local .RData file. Here, lattice and reshape2 are loaded when R is invoked. However, explicitly loading them in the embedded code will be done.
After fixing these two issues, I don't see why lattice graphics can be problematic with knitr. There is no need to print() the plot, and no need to pdf(), either. See the attached PDF I generated.
I'll see if requireing those two libraries in the document resolves the issue. Initially, I did not specify pdf() and added the explicit print() based on that suggestion in this thread. Will test later today.
