[R] Extracting coefficients' standard errors from linear model

[Uli Kleinwechter]

Dear all,

Hope this question is not too trivial...

In order to correct standard errors from an estimation of a fixed 
effects regression model y need to extract the vector of standard errors 
of the coefficients of a simple linear model estimated using

lm(var1~var2+var3+var4)

Unfortunately I can't find out the corresponding function.

Thank you very much for your help.

Uli
