spnGetGrp: Get a group data in the top tab/spec-tree

In spectrino: Spectra Viewer, Organizer, Data Preparation and Property Blocks

Description

Get spectra from one spec-group (matrix) in the top tab/spec-tree. All the spectra in a group are assumed to have common X set of values, so if there is loaded spectrum in different X values, the spectrum is recalculated to fit that reference set.

Usage

spnGetGrp(OnlyChecked,Grp)

Arguments

OnlyChecked	- logical; if true gets only the checked specs.
Grp	- the name(character string) or the index(integer) of a group in the top tab/spec-tree; 0 - active group.

Value

spnGetGrp returns a preprocessed group data in matrix. Spectra are always in rows (one spectrum is one row). The variables are columns, one variable (e.g. mass) is one column.
