HI Gustav,

If you need the combined output:
res<-lapply(1:length(models),function(i) do.call(rbind,lapply(models[[i]],function(x) summary(x)$coef[row.names(summary(x)$coef)%in%c("pm10","ozone","so2"),c(1:2,4)])))
?names(res)<-1:length(res)
res1<-do.call(rbind,lapply(res,function(i) {row.names(i)<-c("pm10","ozone","so2");data.frame(i)}))
names(res1)[2:3]<- c("Std.Error","Pr(>|z|)")
res1
#??????????? Estimate??? Std.Error???? Pr(>|z|)

Hi Arun,

Thanks for taking your time to find a solution.

I have attached a R script that will recreate a?comparable?list from publicly available data. My list is longer and created by various models ?than the one created here. However, the final output is similar to the one produced by script. My interest is to extract only the?coefficients?for ?pm10., ozone and so2 (? Estimate, ?Std. Error ?and?p value) ? ?.?

Thanks

Dear Gustav,
>Thank you for the data.? Could you select a smaller subset of the list and dput() that subset?? Your data is useful, but I would have to recreate list of lists from that to test and sometimes that may not accurate represent the format in your list as it is the summary().

With regards to GLM, GAM, it is good to check the structure of the list (str()). It gives information about whether a `generic` tool could be applied to extract them or not.
