Can I build an array of regrssion model?

Thanks,

But why I can't draw regression line with the following code:

rawData = scan("c:/zyang/mass/data/A01/1.PRN",
what=list(numeric(),numeric()));
len = length(rawData[[1]]);
mod = lm(rawData[[2]]~bs(rawData[[1]],10,degree=1));
plot(rawData[[1]],rawData[[2]],type='l', col="green", xlab="Da/z",
ylab="m/z");
abline(mod,col="red");
