Ad Lines to a Vector Plot

Description

Ad various lines / graphical elements to the plot of a vector like loading or regression vector.

Details

Leave at the default "def" to read in the respective value from the settings.r file. By providing TRUE or FALSE, all or none of the additional graphical elements are drawn on the vector plot. By providing an integer vector in the range [2..5], you can specify which one of the graphical elements should be produced:

• 2 Vertical thin lines dropped from a peak to the x-axis. These can help to see in which WAMAC a peak is falling. (See also below at 4.)

• 3 The "DelGiudice-areas", three wavelength-ranges in the first overtone corresponding to different water structures / properties. The explicit wavelength ranges are defined in the settings.r file in the parameters dga_dga1 to dga_dga3, while the other parameters starting with dga_ are governing size and color. The first area is corresponding to the "single" coherent domain, the second to the gaseous phase in between domains, and the third to the meta-domain consisting of coherent single domains. Please note that this is based upon personal communication with Emilio Del Giudice and can not (yet) be referenced or backed by literature or even experimental findings. So, for now these three wavelength ranges are purely hypothecial.If selected for plotting, the three wavelength-ranges will be indicated by slim lines slightly below the x-axis.

• 4 The WAMACs, i.e. the so called "water matrix coordinates". If selected for plotting, the location of the WAMACs in the first overtone will be indicated by small, slim boxes in alternating colors directly on the x-axis. The colors themselves and the width in the y-axis of the boxes can be specified in the settings.r file in the parameters starting with wamac_.

• 5 Two single markers indicating the wavelengths for humidity will be plotted on the vector plot. The wavelengths, color, size and line-width are specified in the settings.r file in the parameters starting with hum_.

Examples

 ## Not run: 
 fd <- gfd()
 cube <- gdmm(fd)
 plot_pca(cube, ld.adLines=FALSE) # no additional lines in the loading plot 
 plot_pca(cube, ld.adLines=c(2, 4) # only vertical lines and WAMACs in the 
 # loading plot

## End(Not run)
