[rkward-devel] RegModel: standard error missing

[Pep Roca]

Hello:Hello:

I have do a regression analysis with the following code:


AL_FEV_2_DADES <- read.table("AL_FEV_2_DADES.txt", header=TRUE, sep=";")
RegModel.1 <- lm(AL_FEV_2_DADES$FEV~AL_FEV_2_DADES$AL, data=AL_FEV_2_DADES) 
summary(RegModel.1))


but the object RegModel.1 don't show the Std. Error of the coefficient. Only 
show that:


Camí complet: RegModel.1[["coefficients"]]
Classe(s): numeric
Sortida de 'print (RegModel.1[["coefficients"]])':
(Intercept) AL_FEV_2_DADES$AL
-5.3814939 0.0517922 


but if I run the code in the R console of the RKWard, I get all the summary:


> summary(RegModel.1)
Call:
lm(formula = AL_FEV_2_DADES$FEV ~ AL_FEV_2_DADES$AL, data = AL_FEV_2_DADES)

0.8398, Adjusted R-squared: 0.8396 F-statistic: 3424 on 1 and 653 DF, 
p-value: < 2.2e-16


I ma using RKWard 0.4.2. This is a bug?

Thanks a lot. Pep.
