PlotImpVars: Plot selected compounds by their percentage frequency

In xia-lab/MetaboAnalystR3.0: An R Package for Comprehensive Analysis of Metabolomics Data

Description

Plot the important variables of single biomarker model ranked by order of importance

Usage

PlotImpVars(mSetObj=NA, imgName, format="png", dpi=72, mdl.inx, measure = "freq", feat.num = 15)

Arguments

mSetObj	Input the name of the created mSetObj (see InitDataObjects)
imgName	Input a name for the plot
format	elect the image format, "png", of "pdf".
dpi	Input the dpi. If the image format is "pdf", users need not define the dpi. For "png" images, the default dpi is 72. It is suggested that for high-resolution images, select a dpi of 300.
mdl.inx	Model index, -1 selects the model with the best AUC, input 1-6 to view the important features of one of the top six models
measure	Choose to rank features by the frequency of being selected "freq", or the mean importance measure "mean"
feat.num	Input the number of features to include in the plot, by default it is 15.
