perturbate_knn: Generate perturbated expression by k-NN data

In treefit: The First Software for Quantitative Trajectory Inference

Description

Generate perturbated expression from the original expression based on k-NN (k-nearest neighbor) data.

Usage

perturbate_knn(expression, strength = 1)

Arguments

expression	The original expression. The rows and columns correspond to samples and features. The expression is normalized count of features.
strength	How much perturbated. 0.0 is weak. 1.0 is strong.

Value

A perturbated expression as a matrix. The matrix's expression values are perturbated from the original expression values. The shape of the matrix is the same as the original expression. The dimension names of the matrix are also the same as the original expression.
