Simple Subsetting of Single Grain Data from Risø BIN/BINX files

Most measured single grains do not exhibit light and it makes usually sense to subset single grain datasets using a table of position and grain pairs

subset_SingleGrainData(object, selection)

Arguments

object: Risoe.BINfileData (required): input object with the data to subset
selection: data.frame (required): selection table with two columns for position (1st column) and grain (2nd column) (columns names do not matter)

Value

A subset Risoe.BINfileData object

Function version

0.1.0

data(ExampleData.BINfileData, envir = environment())

## set POSITION/GRAIN pair dataset
selection <- data.frame(POSITION = c(1,5,7), GRAIN = c(0,0,0))
