Draw: Draw signals or their PCA scores/loadings.

In PepsNMR: Pre-process 1H-NMR FID signals

Description

Draws FIDs, spectra or their PCA scores/loadings.

Usage

Draw(Signal_data, type.draw = c("signal","pca"),
     output = c("default","window","png","pdf"), 
     dirpath = ".",filename = "%003d", height = 480, 
     width = 640, pdf.onefile = TRUE, ...)

Arguments

Signal_data	Matrix containing the FIDs or spectra, one line per FID/spectrum.
type.draw	Either "signal" or "pca", which calls respectively DrawSignal or DrawPCA to do the drawing.
output	Specifies how to display the drawings: default The output is the default one. window Create a new window for each page. png Create and save a new png image for each image. pdf Create and save a new pdf image for each image.
dirpath	The path to the directory where the png or pdf are outputted.
filename	The filenames of the png and pdf, see argument filename in grDevices::png for more details.
height	Height of the png and pdf in pixels.
width	Width of the png and pdf in pixels.
pdf.onefile	Wen output is set to "pdf" and there are mutliples pages, if pdf.onefile is TRUE, all the pages are in the same file and if it is FALSE all the pages are in a different pdf file.
...	The remaining arguments are passed either to DrawSignal or DrawPCA.

Details

Depending on the type.draw value, it can draw each row of Signal_data in a way described by subtype or the PCA scores or loadings (depending on the type.pca value) of all the FIDs/spectra in Signal_data.

# Draw each signal Real part and Mod in separate png with name end001 end002, ...
# Draw the spectra
require(PepsNMRData)
Draw(FinalSpectra_HS, type.draw = "signal", 
         output="window",subtype="together")

# Draw a PCA
