Returns the ion selection isolation window
The methods return matrices of lower (column low) and upper
(column high) isolation window offsets. Matrices are returned
as a list of length equal to the number of input files (provided as
file names of raw mass spectrometry data objects, see below). By
default (i.e when unique. = TRUE ), only unique offsets are
returned, as they are expected to identical for all spectra per
acquisition. If this is not the case, a message is displayed.
signature(object = "character", unique. = "logical",
simplify = "logical")Returns the isolation window for the
file object. By default, only unique isolation windows
are returned per file (unique = TRUE); if set to
FALSE, a matrix with as many rows as there are MS2
spectra. If only one file passed an input and simplify is
set to TRUE (default), the resulting list of
length 1 is simplified to a matrix.
signature(object = "mzRpwiz", unique. = "logical",
simplify = "logical")As above for mzRpwiz objects.
signature(object = "mzRramp", unique. = "logical",
simplify = "logical")As above for mzRramp object.
