Plots the scores on the first two principal components.
# S3 method for sparsel1pca
plot(x, ...)an object of class sparsel1pca with scores for at least the first two dimensions
arguments to be passed to or from other methods.
This function is a method for the generic function plot, for objects of class sparsel1pca.
sparsel1pca
##for a 100x10 data matrix X,
## lying (mostly) in the subspace defined by the first 2 unit vectors,
## projects data into 1 dimension.
X <- matrix(c(runif(100*2, -10, 10), rep(0,100*8)),nrow=100)
+ matrix(c(rep(0,100*2),rnorm(100*8,0,0.1)),ncol=10)
mysparsel1pca <- sparsel1pca(X)
##projects data into 2 dimensions.
mysparsel1pca <- sparsel1pca(X, projDim=2, center=FALSE, projections="l1")
## plot first two scores
plot(mysparsel1pca$scores)
