Livia,
Try the following:
fit1<-summary(lm(weight~group-1)
summary(fit1)
names(fit1)
#The code above wil fit the model and print the results.
#The statement names(fit1) will give you the components of
#the summary such as
#coefficients, R.squared adj.R.squared, etc.
#You can then access the components, viz.
coeffs<-summary(fit1)$coefficients
#or
RSq<-summary(fit1)$r.squared

Hello,
I would like to fit a linear regression and when I use summary(), I got the
following result:
Call:
lm(formula = weight ~ group - 1)
Residuals:
Min 1Q Median 3Q Max
-1.0710 -0.4938 0.0685 0.2462 1.3690
Coefficients:
Estimate Std. Error t value Pr(>|t|)
groupCtl 5.0320 0.2202 22.85 9.55e-15 ***
groupTrt 4.6610 0.2202 21.16 3.62e-14 ***
---
Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1
Residual standard error: 0.6964 on 18 degrees of freedom
Multiple R-Squared: 0.9818, Adjusted R-squared: 0.9798
F-statistic: 485.1 on 2 and 18 DF, p-value: < 2.2e-16
In fact, I do not need them all. Is there a way of exacting part of the
infomation, like the Coefficient or Multiple R-Squared?
