[R] variables in object names

Is there any way to put an argument into an object name. For example, say I have 5 objects, model1, model2, model3, model4 and model5.  

I would like to make a vector of the r.squares from each model by code such as this:    

rsq <- summary(model1)$r.squared
for(i in 2:5){
rsq <- c(rsq, summary(model%i%)$r.squared) }    

So I assign the first value to rsq then cycle through models 2 through 5 gathering there values. The %i% in my third line indicates which object to draw from. The question is is there any way to pass a variable such as i as part of a name?
