Understanding output stepAIC
After consulting with someone I found out that the  corresponds to a model that would include all the variables, in other words none of the variables were removed. So consider the line in the output for the variable aaa. The listed RSS and AIC are the values for a model that would include all variables but aaa and we see an increase in the RSS and AIC. The other listed results can be considered in the same fashion. The best model is then the one where none are removed since this has the smallest AIC.
