Description Usage Arguments Value Examples

View source: R/omit_std.R

Description

omit_std.powdRafps adjusts phase concentrations in a powdRafps object by removing the concentrations of the internal standard. Relevant information for the calculation is automatically extracted from x$inputs$std and x$inputs$std_conc.

Arguments

x

A powdRafps object derived from afps().

...

other arguments

Value

a powdRafps object with components:

tth

a vector of the 2theta scale of the fitted data

fitted

a vector of the fitted XRPD pattern

measured

a vector of the original XRPD measurement (aligned and harmonised)

residuals

a vector of the residuals (measured minus fitted)

phases

a dataframe of the phases used to produce the fitted pattern and their concentrations

phases_grouped

the phases dataframe grouped by phase_name and concentrations summed

obj

named vector of the objective parameters summarising the quality of the fit

weighted_pure_patterns

a dataframe of reference patterns used to produce the fitted pattern. All patterns have been weighted according to the coefficients used in the fit

coefficients

a named vector of coefficients used to produce the fitted pattern

inputs

a list of input arguments used in the function call
