Store the models into a list and the use an apply-function. x=1:10 #this creates some example data y=rnorm(10) m1=lm(x~y) m2=lm(x~1) Models <- list(m1, m2) lapply(Models, summary)

I have tried: x=1:10 #this creates some example data y=rnorm(10) m1=lm(x~y) m2=lm(x~1) sum.lms=function(x)summary(paste("m",x,sep="")) sum.lms(1:2) but the paste() function always returns "m1" "m2" in quotation marks instead of m1 m2 Do you know a way around this? I guess I would need to use expression() or substitute() but I don´t know how to construct m1, m2... without the quotation marks. Thanks very much for your help!
