PlotPLS.Imp: Plot PLS important features
In flajole/MApckg: R package of MetaboAnalyst functions

Description Usage Arguments See Also

There are two importance measures in PLS-DA : one is variable importance in projection (VIP) and the other is weighted sum of absolute regression coefficients (coef.). The colored boxes on the right indicate the relative concentrations of the corresponding metabolite in each group under study.

`dataSet`	List, data set object generated by `MS_to_MA` function.
`analSet`	List, containing the results of statistical analysis (can be just an empty list).
`imgName`	Image file name prefix.
`format`	Image format, one of: "png", "tiff", "pdf", "ps", "svg"
`dpi`	Image resolution.
`width`	Image width.
`type`	Importance measure. `"vip"` - for variable importance in projection (VIP); `"coef"` - for weighted sum of absolute regression coefficients.
`feat.nm`	The number of component used for VIP calculation.
`feat.num`	The number of top features to plot.
`color.BW`	If `TRUE`, gray scale is used.
