Description

This function is designed for a quick analysis and visualization of the data integrated by integrate() function. It takes 3 compulsory arguments name, Assay and choice. The type of analysis should be selected through the "choice" argument. This function acts as a wrapper around a collection of functions of package "factoextra" and "corrplot" and thus can take additional arguments specific and non-conflicting to such functions.

Usage

2
analyse_variables(name, Assay, choice, title = NULL, PC = 1,
var_type = "contrib", ...)

Arguments

name

Name of the "PCA" object

Assay

Name of an Assay.

choice
1 = variance barplot
2 = Loadings of cell lines on selected PCs
3 = hCorrelation matrix
4 = Squarred loadings of Cell lines on a PC
5 = Contribution of Cell lines on a PC

for details of the choices see the vignette
title

PC

used in choice = 4 and 5. Indicates the PC on which choice 4 and 5 will depend. default = 1

var_type

used in choice = 2. available options are: "coord", "cos2" and "contrib". default = "contrib"

...

extra arguments passed through the functions imported from various packages. See vignettes for details.
