comment How to analyze elastic net fitted model coefficients
@jmnavarro I see your updates to the question, and appreciate them. See if you can distill your script down to the essence of the problem. Can you reproduce it with a subset of the columns from your original dataset? Can you reproduce it with a subset of rows from your original dataset? Can you reproduce it with a simulated dataset in a fresh R session? It's hard for us to help you debug your code without being able to run it on our own machines =D

@jmnavarro Please post an example matrix of binary data that generates more coefficients than expected. Until you do so, I (and everyone else on this site) will assume you just have a bug in your code.

@jmnavarro You need to post more than an excerpt. You need to post a data sample and code that reproduces the problem EXACTLY.

comment Import stock price from Yahoo Finance into R?
@acabahe It still runs fine for me. Make sure you grab everything from require(quantmod) to the trailing } all by itself on the last line. You'll need to wait at least 5 minutes before you'll see a graph show up.
