roc_surro {MiMIR}

roc_surro

Description

Function that creates a ROC curve of the selected metabolic surrogates as a plotly image

Usage

roc_surro(surrogates, bin_phenotypes, x_name)

Arguments

surrogates

numeric data.frame of metabolomics-based surrogate values by Bizzarri et al.

bin_phenotypes

logic data.frame of binarized phenotypes

x_name

vector of strings with the names of the selected binary phenotypes for the roc

Value

plotly image with the ROC curves for one or more selected variables

Examples

require(pROC)
require(plotly)
require(foreach)
require(MiMIR)

#load the dataset
met <- synthetic_metabolic_dataset
phen<- synthetic_phenotypic_dataset

#Calculating the binarized surrogates
b_phen<-binarize_all_pheno(phen)
#Apply a surrogate models and plot the ROC curve
surr<-calculate_surrogate_scores(met, phen, MiMIR::PARAM_surrogates, colnames(b_phen))
#Plot the ROC curves
roc_surro(surr$surrogates, b_phen, "sex")
