Plot CV Error with 1-SE Rule for u — plot_cv

For each principal component (PC), plots cross-validation (CV) error versus the sparsity tuning parameter (gamma) for the u-direction. The red dashed line indicates the 1-SE rule threshold, and the selected optimal gamma is highlighted. Optionally, standard error bars (±1 SE) can be displayed.

Usage

plot_cv_u(ReMPCA_obj, show_se = TRUE, ...)

Arguments

ReMPCA_obj: Output list from the ReMPCA routine.
show_se: Logical. If TRUE, adds standard error bars to each point. Default is TRUE.
...: Additional plotting options passed to plot().

Value

Generates base R plots side-by-side for each PC.
