[R] save the output of summary(lmList(x)) into a dataframe

[Cecilia Carmo]

Hi r-helpers!

I need to save the output of summary() function that I’ve 
runned like this:
z<- lmList(y~x1+x2| x3, 
na.action=na.omit,data1,subset=year==1999)
w<-summary(z)
The output (w) is something like this:
Call:
   Model: y ~ x1 + x2 | x3
    Data: data1
Coefficients:
    (Intercept)
         Estimate    Std. Error       t value  Pr(>|t|)

Residual standard error: 0.2261486 on 1522 degrees of 
freedom

I would like to have this output  in a dataframe like 
this:
x3  intercept  x1   x2   Std. Error   t value   Pr(>|t|)
1

Anyone knows if it is possible and how?

Thanks in advance,
