# Interpretting LASSO variable trace plots

I am new to the glmnet package, and I am still unsure of how to interpret the results. Could anyone please help me read the following trace plot?

The graph was obtaining by running the following:

library(glmnet)
return <- matrix(ret.ff.zoo[which(index(ret.ff.zoo)==beta.df$date[2]), ]) data <- matrix(unlist(beta.df[which(beta.df$date==beta.df$date[2]), ][ ,-1]), ncol=num.factors) model <- cv.glmnet(data, return, standardize=TRUE) op <- par(mfrow=c(1, 2)) plot(model$glmnet.fit, "norm",   label=TRUE)
plot(model\$glmnet.fit, "lambda", label=TRUE)
par(op)
