plot.clpca {logisticPCA}

R Documentation

Plot convex logistic PCA

Description

Plots the results of a convex logistic PCA

Usage

## S3 method for class 'clpca'
plot(x, type = c("trace", "loadings", "scores"), ...)

Arguments

`x`	convex logistic PCA object
`type`	the type of plot `type = "trace"` plots the algorithms progress by iteration, `type = "loadings"` plots the first 2 PC loadings, `type = "scores"` plots the first 2 PC scores
`...`	Additional arguments

Examples

# construct a low rank matrix in the logit scale
rows = 100
cols = 10
set.seed(1)
mat_logit = outer(rnorm(rows), rnorm(cols))

# generate a binary matrix
mat = (matrix(runif(rows * cols), rows, cols) <= inv.logit.mat(mat_logit)) * 1.0

# run convex logistic PCA on it
clpca = convexLogisticPCA(mat, k = 2, m = 4, main_effects = FALSE)

## Not run: 
plot(clpca)

## End(Not run)
