Changes in version 1.0 Bioconductor release 3.12 package. Changes in 1.0.5 - filterIntensity supports passing of additional parameters to the used filter function (issue 164). Changes in 1.0.4 - Fix show,ProcessingStep (issue #162). Changes in 1.0.3 - Fix issue with labelCol in plotSpectra (issue #157). - Avoid calling par(mfrow = in plotSpectra if only a single spectrum is plotted. Changes in 1.0.2 - Add a Spectra,ANY constructor to replace the Spectra,DataFrame and Spectra,character constructor methods. Changes in 1.0.1 - Fix export of empty spectra with MsBackendMzR (see issue #145). Changes in version 0.99 Changes in 0.99.11 - Re-add mz and intensity as core spectra variables. Changes in 0.99.10 - Fix in spectraData<-,Spectra to avoid removing m/z and intensity values (issue #146). - Add default implementations of filter functions for MsBackend. Changes in 0.99.9 - Fix in Spectra,character constructor to ensure the backend is changed even if source inherits from backend (issue #143). Changes in 0.99.8 - combineSpectra applies data processing steps in the processing queue prior to combination (issue #140). Changes in 0.99.7 - Fix problem in dropNaSpectraVariables that would also drop m/z and intensity values for most backends (issue #138. Changes in 0.99.6 - Support intensity in filterIntensity method to be a function to enable peak intensity-based filtering of spectra (issue #126). Changes in 0.99.5 - Add filterMzRange and filterMzValues to filter spectra based on an m/z range or a list of target m/z values, respectively. Changes in 0.99.4 - Add export,MsBackendMzR to export spectra data to mzML or mzXML file(s). - Add an export,MsBackend method to allow backends to take care of data export. - Refactor export,Spectra to use the MsBackend class to export the data. - Change parameter source in Spectra,character to MsBackendMzR and set parameter backend = source. Thus by default, the import backend will also be used to store the data. Changes in 0.99.3 - Replace lapply,Spectra with spectrapply,Spectra. Changes in 0.99.2 - Replace asDataFrame,MsBackend with spectraData,MsBackend. - Replace asDataFrame<-,MsBackend with spectraData<-,MsBackend. - Replace as.list,MsBackend with peaksData,MsBackend. - Replace replaceList<-,MsBackend with peaksData<-,MsBackend. - Replace as.list,Spectra with peaksData,Spectra and add methods to coerce a Spectra to a list or SimpleList. Changes in 0.99.0 - Add reset method. - Add processing by chunk to compareSpectra.
