plot_alpha: Plot for the optimal alpha

Description

Plot for the mean with the standard deviation of cost function and alpha

Usage

plot_alpha(opt_results)

Value

No return value, showing the mean and standard deviation of cost function for each alpha value.

Arguments

opt_results

opt_results is from either optimal_alpha_boot or optimal_alpha_cv

Examples

library(ManifoldOptim)
library(rSDR)
utils::data("ionosphere", package = "fdm2id")
X<-as.matrix(ionosphere[,c(1:33)])
Y<-ifelse(ionosphere[,34]=='b',0,1)
Y<-matrix(Y,length(Y),1)
set.seed(2435)
