Yihui,
I assumed that reading in the *.csv file would create a local .RData

All fixed now. After adding the specific libraries the chuck calling
xyplot() to produce the graphic caused an error when I tried to generate a
dvips preview:
LaTeX Error: File
I guess you didn't tell us you were compiling the document with dvips
(BTW, I'm surprised that dvips is still alive today...), otherwise the
solution would be simply to use the postscript device instead of the
default pdf device (i.e. use the chunk option dev='postscript').
Hopefully you learned

David,
I did leave that off the example file, but it make no difference. The

You didn't library(reshape) and library(lattice). Hence it is not a
self-contained reproducible example.
After fixing these two issues, I don't see why lattice graphics can be
problematic with knitr. There is no need to print()

I'd recommend starting with a simpler .Rmd or .Rnw file, rather than
using it with lyx. The basic .Rmd file below works for me without any
further adjustments:
# Lattice test
```{r}
library(lattice)
xyplot(mpg ~ wt, data = mtcars)
```

I don't actually use lattice very much, but I have no difficulty setting up a
lattice plot in a knitr/rmarkdown file, and can think of no reason why you
might have concluded that knitr does not support lattice.

Roy,
Thanks. I'll certainly read that article.
Carpe weekend,

You shouldn't be explicitly opening a device in a knitr document. I think
maybe you should post a minimal document so we can figure out what's going
wrong.

Agreed. Attached are the raw data (carlin.csv) and a
