xrd.get.AllPeaks: Finds all peaks in an XRD spectrum

In thomasgredig/rigakuXRD: X-Ray Diffraction Data Import and Analysis

Finds all peaks in an XRD spectrum

Description

Attempts to find peaks in an XRD spectrum and return a list of angles with the peak locations. (Use with caution, might find additional peaks.)

Usage

xrd.get.AllPeaks(
  data,
  min.Prominence = 5,
  Try.Sigma = c(0.2, 0.1, 0.05, 0.3),
  deltaTheta = 5,
  Range = c(0, 90)
)

Arguments

data	data frame with intensity and 2 theta angle.
min.Prominence	minimum prominence in percent (optional).
Try.Sigma	vector with peak widths used to start fitting (optional).
deltaTheta	search area around main peak (optional).
Range	range to search for peaks (optional).

Value

sorted vector with peak positions with 0.01 degree precision.

Examples

filename = xrd.getSampleFiles('asc')
d = xrd.import(filename)
xrd.get.AllPeaks(d, deltaTheta = 2, Try.Sigma = c(0.1),  Range = c(42, 46))
