ESR.Spectrum: ESR.Spectrum class objects
In tzerk/ESR: Package for Electron Spin Resonance Dating Data Analysis

Description Usage Arguments Format Slots Methods Author(s) Examples

Objects of class ESR, ESR.Spectrum are R6 objects and hence are usable in a more typical object-oriented language than R. For the user the main difference to R's internal S3 and S4 object implementation is that methods for R6 objects belong to the object itself. See details.

`x`	`data.frame` XY data of the ESR spectrum
`originator`	`character` name of the function call that created this object
`data`	`data.frame` XY values of the ESR spectrum
`par`	`data.frame` experimental parameters
`order`	`integer` order of the differential
`v`	`numeric` The microwave frequency in GHz
`H`	`numeric` A vector of magnetic field values in Gauss
`interval`	`numeric` a vector of length two specifying the range of x-values where peaks are searched
`th`	`numeric`: an integer specifying the number of neighbouring values to compare each x-value to
`...`	Further arguments passed to method specific functions.

R6Class generator objects

originator: character Name of the function call that created this object
data: data.frame XY data of the ESR spectrum
parameter: data.frame experimental parameters
type: character currently unused

new(originator, data): Initialize a new object of class ESR.Spectrum
set_data(data): Sets the data of the object
set_origin(originator): Sets the originator of the object
set_par(par): Sets the experimental settings of the object
get_diff(x, order = 1, ...): Returns the differential of the spectrum
get_integral(x): Returns the integrant of the spectrum
get_spline(x, ...): Returns a smoothed spectrum using the smooth.spline function
get_gvalues(v, H, x): Calculates and returns the g-values of the spectrum
get_peaks(x, interval, th = 10): Returns a vector of local minima and maxima in the spectrum. For details see find_Peaks.
