[R] Problems with displaying Regression Results

[arun]

Hi,


You could change ?options()
options("scipen")
#$scipen
#[1] 0
 print(1e5)
#[1] 1e+05
op<- options()
options(scipen=20)
 print(1e10)
#[1] 10000000000


Using the example from ?lm()
ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14)
  trt <- c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69)
      group <- gl(2, 10, 20, labels = c("Ctl","Trt"))
      weight <- c(ctl, trt)
      lm.D9 <- lm(weight ~ group)
 summary(lm.D9)


 coef(summary(lm.D9))
#            Estimate Std. Error  t value                Pr(>|t|)
#(Intercept)    5.032  0.2202177 22.85012 0.000000000000009547128
#groupTrt      -0.371  0.3114349 -1.19126 0.249023165973006332941


options(op) #reset
coef(summary(lm.D9))
#            Estimate Std. Error  t value     Pr(>|t|)
#(Intercept)    5.032  0.2202177 22.85012 9.547128e-15
#groupTrt      -0.371  0.3114349 -1.19126 2.490232e-01

Subject: [R] Problems with displaying Regression Results

Hello guys

I have the following questions.
I am currently running various regressions using the lm() command.
As a result I get the following:
<http://r.789695.n4.nabble.com/file/n4673551/Bildschirmfoto_2013-08-12_um_11.40.56.png> 

My question is why R always adds the "e"s although for example they could
just write -2610 as the upper left value which would be less confusing than
with the "e"s?

Many thanks for your help, I really appreciate it.
Tom
