Dear R users,
I have problem with extracting coefficients from a
object. Here, X (predictor)and Y (response) are two matrix , I am regressing
X ( dimensions 10 x 20) on each of columns of Y[,1] (10 x 1) and want to
store the coefficient values. I have performed a Elastic Net regression and
I want to store the coeffcients in each iteration. I got an error message .
I do not know where is the problem???? Please help me.
Thanks
*Code:*
-------------------------------------------------------
library(elasticnet)
X<-matrix(rnorm(200),ncol=20)
Y<-matrix(rnorm(200),ncol=20)
loop <- 20
size <- 20
enres<-matrix(nrow = size, ncol = loop)
fit<-matrix(nrow = size, ncol = loop)
store<-matrix(nrow = size, ncol = loop)
for(j in 1: 10)
print (paste(j,"/200",sep=""))
{
enres<-enet(x=X,y=Y[,j],lambda=1,normalize=TRUE,intercept=TRUE)
fit<-predict.enet(enres, X, type="coefficients")
store[,j]<-fit$coefficients
}
