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)])))

Subject: Re: Select components of a list
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) .

>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().

>>If you can email (smartpink111 at yahoo.com) me the `list` (dput(list)), I can take a look at it. Probably, you understand that my previous solution was just guesswork. 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.
