hello I tried to use lars() but neither with my own data nor with the sample data it works. I get in both cases the following error prompt:
data(diabetes) par(mfrow=c(2,2)) attach(diabetes) x<-lars(x,y)
Error in one %*% x : requires numeric matrix/vector arguments
x<-lars(x,y, type="lasso")
Error in one %*% x : requires numeric matrix/vector arguments
x<-lars(x,y, type="lar")
Error in one %*% x : requires numeric matrix/vector arguments due to the prompt "requires numeric matrix..." I changed the variables to matrix/vector or used different columns but it doesn't work either. what does "error in one %*%x mean? thanks in advance, cheers Martin
