I suspect that this might be a bit basic, but here goes anyway...
I am soon to run a large number of linear regressions and I would like to

dataframe as a summary of the overall block of analyses. I can

lm1<-lm(ASTF~Year,na.action=na.omit,subset=yr10==T)
a1<-lm1$coefficients[1]
b1<-lm1$coefficients[2]
out1<-cbind("ASTF","1996-2005",lm1$coefficients[1],lm1$coefficients[2])
However, I also would like to extract the following too:
1) the number of data points in the analysis, n
