Maybe someone can help with the following problem:
I have a source file containing the following code for plotting:

pdf(file = 'data/mario/boxplot.pdf')
bwplot(sig100 ~ target | group, data = fish, main = 'Boxplot der
Signale in 100 Zellen nach Gruppe', xlab = '', ylab = 'Anzahl der
Signale')
dev.off()

pdf(file = 'data/mario/xyplot.pdf')
xyplot(sig100 ~ target | group, data = fish, main = 'Signale in 100
Zellen nach Gruppen', xlab = '', ylab = 'Anzahl der Signale',
 	panel = function(x,y, ...) {
 		panel.grid(h = -1, v = -1)
 		panel.xyplot(x,y, jitter.x=TRUE)
 		panel.lmline(x,y, lty = 2, col = 3)})
dev.off()

If I run the file from R with
source('lib/analysis_mario.R')
a two pdf-files will be created but they cannot be read.

When I use
source('lib/analysis_mario.R', echo=TRUE)
the files are created correctly.

Actually I don't want the echo, so what can I do to plot correctly and
omit the echo in one run.

I use
