Purity spectra plot
## S3 method for class 'mcrpure' plotPuritySpectra( obj, comp = seq_len(obj$ncomp), type = "l", col = mdaplot.getColors(obj$ncomp), show.lines = TRUE, lines.col = adjustcolor(col, alpha.f = 0.75), lines.lty = 3, lines.lwd = 1, ... )
obj: mcrpure object
comp: vector of components to show the purity spectra for
type: type of the plot
col: colors for the plot (should be a vector with one value for each component in obj)
show.lines: if TRUE show the selected pure variables as vertical lines
lines.col: color for the selected pure variable lines (by default same as for plots but semitransparent)
lines.lty: line type for the purity lines
lines.lwd: line width for the purity lines
...: other parameters suitable for mdaplotg
The plot shows weighted purity value of each variable separately for each specified component.
