xrd.get.PeakStats: Fits a Gaussian Function to XRD data

In thomasgredig/rigakuXRD: X-Ray Diffraction Data Analysis Package for Rigaku Data Sets

Fits a Gaussian Function to XRD data

Description

usually run after a peak is identified through its location

Usage

xrd.get.PeakStats(
  TwoTheta,
  Intensity,
  peakPos,
  Try.Sigma = c(0.2, 0.1, 0.05, 0.3),
  verbose = FALSE
)

Arguments

TwoTheta	2q angle
Intensity	XRD intensity
peakPos	specific 2q angle of peak position
Try.Sigma	vector with peak widths used to start fitting
verbose	logical, if TRUE output additional information

Value

background, amplitude, position, width + 4 std. errors
