rSDR (version 1.0.3.0)

plot_rSDR: Projected data plotting

Description

Function for plotting of projected_data from rSDR results.

Usage

plot_rSDR(projected_data,Y,Y.name,colors=NULL)

Value

No return value, visualizing reduced-dimensional data using 1D, 2D, or 3D projections. When the reduced dimension exceeds three, pairwise scatter plots are automatically generated.

Arguments

projected_data

projected data from rSDR results.

Y

an \(n \times 1\) numeric matrix.

Y.name

label for y-axis

colors

Assign specific colors to each level of the response variable.

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)
ionosphere$V35<-factor(ionosphere$V35,levels=c('b','g'),labels=c('Bad','Good'))
set.seed(2435)
# \donttest{
sdr_result<-rSDR(X=X, Y=Y, d=3, alpha=0.3,maxiter=1000,tol=1e-7)
plot_rSDR(projected_data=sdr_result$projected_data,Y=ionosphere$V35,
Y.name='group',colors=c("#374E55FF", "#DF8F44FF"))
