fit3 = mod3$fit()
Error in .Call("admm_dantzig", .self$x, .self$y, .self$lambda, .self$nlambda, :
"admm_dantzig" not available for .Call() for package "ADMM"
Yeah. This is because the Dantzig selection has been removed in the current version, since it is very hard to converge using ADMM. It may require better algorithm to solve.
When I run this command, I find a bug.
