In vjcitn/BiocSklearn: interface to python sklearn via Rstudio reticulate

use sklearn IncrementalPCA procedure

Description

use sklearn IncrementalPCA procedure

Usage

skIncrPCA(mat, n_components = 2L, batch_size = 5L, ...)

Arguments

mat	a matrix – can be R matrix or numpy.ndarray, if the latter it must be set up in a basilisk persistent environment, and that is not currently demonstrated for this package.
n_components	number of PCA to retrieve
batch_size	number of records to use at each iteration
...	passed to python IncrementalPCA

Value

matrix with rotation

Examples

dem = skIncrPCA(iris[,1:4], batch_size=25L)
dem2 = skIncrPCA(iris[,1:4], batch_size=25L, n_components=2L)
