I would like to be able to do something like this: <<echo=F,fig=T,width=mywidth>>= ... @ with mywidth set in a previous code chunk. Is there a way to do this in Sweave? (Sorry for two questions in a row, I have been saving these up.) -- Michael

Consider this plot: xyplot(mpg ~ disp | cyl, mtcars, strip=F, strip.left=T, layout=c(1, 3), scales=list(relation="free"), par.settings=list(strip.background=list(col="transparent"))) I want to have the "cyl" strip labels on the left side of the axis. Is this possible? Failing that, is it possible to remove the left axis and display it on the right

I am using R 2.4.0 and lattice to produce some xyplots conditioned on a factor and a shingle. The shingle merely chops up the data along the x-axis, so it is easy to identify which part of the shingle a panel is in by looking at the x-axis markings. I only want to have a strip at the top for the factor. Is this possible? I looked into calculateGridLayout() and it seems to me that there

barchart(Titanic, stack=F) produces a very nice horizontal barchart. Each panel has four groups of two bars. barchart(Titanic, stack=F, horizontal=F) doesn't produce the results I would have expected, as it produces this warning message: Warning message: y should be numeric in: bwplot.formula(x = as.formula(form), data = list(Class = c(1, And it results in each panel having 22 groups of

I have been using Aspell on a Linux system, but it doesn't understand the noweb chunks, which I'd rather it not spellcheck. I can run it on the generated .tex files, but then changes I make during the spellcheck will not be propagated back to the original source. Any suggestions on how to spellcheck Sweave documents? I see from a search that some people seem to be trying Flyspell on

I would like to have an automatic traceback printed on error. Is there a way to do this? options(error=traceback) seems to print the previous error, not the current error. I'm guessing this is because the traceback is not set until the error handler is done running. > options(error=traceback) > stop("1") Error: 1 No traceback available > stop("2") Error: 2 1:
