[R] find lowest AIC of a LM

I have a simple linear model with 4/5 variables that I am trying to fit.
I would like to find the lowest AIC value with any combination of all
the variables. I would like to implement this with a while/for loop.
Possibly I would like to generalize this so then I can use it when I
have many more variables. I do not want to use step AIC. At the moment I
am doing it manually but I would like to automate the process because I
have many species. I want to compute all possible combinations with all
the variables and know which combination gives the lowest AIC.
My function looks like this
I cannot seem to find a library that has a function that does this
