powdRlib: Create an XRPD reference library
In powdR: Full Pattern Summation of X-Ray Powder Diffraction Data

Description Usage Arguments Value Examples

A constructor function for creating a powdRlib object from two tables of data. The resulting powdRlib object is required when using fps or afps.

1	powdRlib(xrd_table, phases_table, check_names)

`xrd_table`	A data frame of the count intensities of the XRPD reference patterns, all scaled to same maximum intensity, with their 2theta axis as the first column.
`phases_table`	A data frame of the required data (phase ID, phase name, and reference intensity ratio) for each reference pattern.
`check_names`	A logical argument defining whether the column names in the data supplied in `xrd_table` are syntactically valid variable names and are not duplicated. Default = `TRUE`.

a powdRlib object with components:

`xrd`	a data frame of the count intensities of the reference patterns
`tth`	a vector of the 2theta axis
`phases`	a 3 column data frame of the IDs, names and reference intensity ratios of the reference pattern

#load an example xrd_table
data(minerals_xrd)
#load an example phases_table
data(minerals_phases)

#Create a reference library object
xrd_lib <- powdRlib(xrd_table = minerals_xrd,
                    phases_table = minerals_phases)
