Dear all,
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
extract a number of details from the models, and then collate them in a
dataframe as a summary of the overall block of analyses. I can successfully
extract the intercept and slope by using, for example:
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
2) the standard error of the slope
3) the P value
4) the R-squared value
Is it possible to extract these parameters in the same way as the slope and
intercept, to save a lot of typing?
Any help much appreciated!
