You called the lm method for summary() on an object of class c("aovlist",
"listof"). You should not expect a method for one class to work on an
Hi Cristiano,
Might be the data you have for "dv". I don't seem to get the problem.
dv<-sample(1:6,15,TRUE)
subject<-factor(rep(paste("s",1:5,sep=""),each=3))
myfactor_c<-factor(rep(paste("f",1:3,sep=""),5))
mydata_c<-data.frame(dv,subject,myfactor_c)
mod_c<-aov(dv~myfactor_c+Error(subject/myfacto
Dear all,
I am trying to visualize the regression coefficients of the linear model
that the function aov() implicitly fits. Unfortunately the function
summary.lm() throws an error I do not understand. Here is a toy example:
dv <- c(1,3,4,2,2,3,2,5,6,3,4,4,3,5,6);
subject <-
factor(c("s1","s1
?coef
There are many introductory texts on R... I recommend getting a few.

Hi all,
I have run a ridge regression as follows:
reg=lm.ridge(final$l~final$lag1+final$lag2+final$g+final$g+final$u,
lambda=seq(0,10,0.01))
Then I enter :
select(reg) and it returns: modified HKB estimator is 19.3409
modified L-W estimator is 36.18617
