[R] Problem with na.action within own function

Dear R Community, I am trying to build a very simple function which uses lm and coeftest to return a coefficient matrix with heteroskedasticity robust standard errors. The function is the following: reg=function(formula,data,na.action){ res=lm(formula=formula,data=data,na.action=na.action) h
