[R] linear regression: Is there a way to get the results of lm as variables

2009-10-21 Thread CE.KA 

Hi R users

I used R to get the results of a linear regression

reg-lm(y~x)

here are the results:

# Call:
# lm(formula = donnees$txi7098 ~ donnees$txs7098)
# 
# Residuals:
   
#   Min1QMedian3Q   Max 
   
# -0.037971 -0.013373 -0.004947  0.010618  0.053235 
  
# 
# Coefficients:
# Estimate Std. Error t value Pr(|t|)
# (Intercept)  0.085470.03028   2.822 0.011738 *  
# donnees$txs7098  0.623060.12847   4.850 0.000150 ***
# ---
# Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 
#   
 
# Residual standard error: 0.02199 on 17 degrees of freedom 
  
# Multiple R-squared: 0.5805, Adjusted R-squared: 0.5558
  
# F-statistic: 23.52 on 1 and 17 DF,  p-value: 0.0001502 

I know how to get  the coefficients as variable
for exemple: 
reg$coefficients[1]=0.08547 (Estimate )
reg$coefficients[2]=0.62306 (Estimate )

My question is:
Is there a way to get the other results of lm as variables?
-Std. Errors?
-t value?
-Pr(|t|) ?   
-Residual standard error?
-Multiple R-squared?
-F-statistic?

Best regards

Hi CE.KA,

Take a look at the following:

# Data
set.seed(123)
x - rnorm(100)
y - 2 + 1.5*x + rnorm(100)

# Regression model
reg - lm(y ~ x)

# The summary
summary(reg)

# Objects present in the summary()
names(summary(reg))

# Extracting the coefficients
summary(reg)$coeff

HTH,
Jorge
