pickSARdata: SAR data set selection

Description

Extracting SAR data sets according to certain criteria (recycling ratio, recuperation, figure-of-merit and reduced-chi-square values of fitted growth curves).

Usage

pickSARdata(Data, model = "gok", origin = FALSE, weight = TRUE,  rcy.interval = NULL, rcp1.limit = NULL, rcp2.limit = NULL,  fom.limit = NULL, rcs.limit = NULL, outfile = NULL)

Arguments

Data

data.frame(required): data used for constructing growth curves, it should contain five columns (i.e., Grain.NO, SAR.Cycle, Dose, Signal, and Signal.Err), see SARdata for details

model

character(with default): model used for growth curve fitting, see fitGrowth for available models

origin

logical(with default): force the fitted growth curve to pass the origin or not

weight

logical(with default): perform growth curve fitting using a weighted or an un-weighted procedure, see function fitGrowth for details

rcy.interval

vector(optional): a two-element vector indicating the lower and upper limits on recycling ratio, for example, rcy.interval=c(0.9,1.1)

rcp1.limit

double(optional): upper limit on recuperation1 (i.e., the ratio of standardised zero regenerative dose signal to standardised natural dose signal) in percent

rcp2.limit

double(optional): upper limit on recuperation2 (i.e., the ratio of standardised zero regenerative dose signal to maximum standardised regenerative dose signal) in percent

fom.limit

double(optional): upper limit on figure-of-merit (FOM) values of fitted growth curves in percent

rcs.limit

double(optional): upper limit on reduced-chi-square (RCS) values of fitted growth curves

outfile

character(optional): if specified, quantities related to selected Grain.NO will be written to a CSV file named "outfile" and saved to the current work directory

Value

Return a list that contains the following elements:

Data

Selected SAR data sets

tab

quantities related to seleted Grain.NO, such as recycling ratio, recuperation, FOM, RCS, etc

failFit.NO

Grain.NO failed in growth curve fitting

reject.NO

rejected Grain.NO
