"Unexpected symbol" often means missing punctuation.
In this case, it looks like
panel=function(){panel.xyplot(Kalibrierung$Spannung,Kalibrierung
$Magnetfeld)panel.abline(reg=test)}
this argument is missing a semi-colon ";" before "panel.abline".
panel=function(){panel.xyplot(Kalibrierung$Spannung,Kalibrierung
$Magnetfeld); panel.abline(reg=test)}

in addition to Richard:
I would try to write out the function over multiple lines:
panel=function(){
panel.xyplot(Kalibrierung$Spannung,Kalibrierung$Magnetfeld)
panel.abline(reg=test)}
solven the problem you had, as would the semicolon, but in my opinion it
make the command more readable. You can also use '...' in the panel
function:
panel=function(...){
panel.xyplot(...)
panel.abline(reg=test)}
I like this because I don't have think about what to pass on to
panel.xyplot.
hope this helps,
Paul
