Stargazer in R : Summary statistics by group

Question

I have a panel data with TOT firms, in which variables are analyzed for 11 years. Do you know a "special" STARGAZER code which permit to have a descriptive statistics of the variables for each year? I already got summary statistics of the whole sample, but I need it for each year. Thank you in advance.

I tried:

stargazer(subset(data[c("Var1","Var2","Var3"), data$YEAR], 
                 type="text" , title="Summary Statistics" , 
                 out="samplesummary.html")

But it doesn't work.
