[R] how to get coefficients of regression or Anova

[John Sorkin]

Kum-Hoe,
You need to used the summary function. I hope the example below will
help you get the coefficeints:

 myfit<-lm(y1~x1)
 coefficients(summary(myfit))

Hi R Gurus!

I conducted regression and anova followings :

Coefficients:
                                  Estimate Std. Error t value Pr(>|t|)
(Intercept)                       6.07e-01   5.95e-02   10.19  < 2e-16
***
nemp                              2.87e-06   1.04e-07   27.63  < 2e-16
***
as.factor(corridor1)A   -8.81e-02   2.13e-02   -4.14  3.6e-05 ***
as.factor(corridor1)B    1.75e-01   3.02e-02    5.78  8.8e-09 ***
as.factor(corridor1)C      1.09e-02   2.74e-02    0.40  0.69196
as.factor(corridor1)D      2.58e+00   1.56e-01   16.51  < 2e-16 ***
as.factor(corridor1)E -6.75e-03   1.76e-02   -0.38  0.70107
...

I do want to get the following results:
Coefficients:
                                  Estimate Std. Error t value Pr(>|t|)
(Intercept)                       6.07e-01   5.95e-02   10.19  < 2e-16
***
nemp                              2.87e-06   1.04e-07   27.63  < 2e-16
***
as.factor(corridor1)        ?????       ??????    ?????   ?????*

But I do not know how to get coefficients of regression or Anova
model.
Thanks in advance,
