Changes in version 1.16

mandatory spectra variables for a backend.

Fixes issue #5.
Changes in 1.15.9
- Restructure and reorganize documentation for Spectra.
Changes in 1.15.8
- Refactor the Spectra() constructor method: better support for
initialization of backends that define their own specific
parameters.
Changes in 1.15.7
- Change estimatePrecursorIntensity() to a method to avoid
overrides/clashes with the same-named implementation in xcms.
Changes in 1.15.6

variables "mz" and "intensity" are not by default removed.
Changes in 1.15.5
- Add new filterPeaksRanges() function to filter mass peaks by ranges
on numeric spectra or peak variables.
Changes in 1.15.3
- For evaluation of the Spectra's processing queue: call functions
from the MetaboCoreUtils directly through their namespace
(MsCoreUtils::) to avoid errors if performed in parallel on Windows
machines or if called on a re-loaded object.
- New asDataFrame() function to convert a (small) Spectra object into
a long DataFrame.
Changes in 1.15.2
- Add dataStorageDataPath() and dataStorageDataPath<- methods to allow
updating/adapting the path of the data storage files of backends
supporting that issue #321.
Changes in 1.15.1
- Improve documentation for combineSpectra() and combinePeaks() issue
#320.
Changes in version 1.13
Changes in 1.13.8
- Add estimatePrecursorMz() function to estimate the precursor m/z for
DDA fragment spectra from previous MS1 spectra issue #315.
Changes in 1.13.7
- Move generics backendBpparam(), backendParallelFactor() and
supportsSetBackend() to ProtGenerics. Required ProtGenerics version
1.35.4 or higher.
Changes in 1.13.6
- Add filterRanges() and filterValues() functions to allow filtering
of a Spectra object based on ranges or similarities of any existing
spectraData variables.
Changes in 1.13.5
- Move generics to ProtGenerics. Requires ProtGenerics version 1.35.3.
Changes in 1.13.4
- Add entropy and nentropy functions to allow to calculate the
(normalized) entropy for each spectrum.
Changes in 1.13.3
- Fix issue in setBackend that might cause chunk-wise processing to be
not run.
Changes in 1.13.2
- Add possibility to enable and perform chunk-wise (parallel)
processing to Spectra: add functions processingChunkSize,
backendParallelFactor and processingChunkFactor to set or get
definition of chunks for parallel processing. All functions working
on peaks data use this mechanism which is implemented in the
internal .peaksapply function. The Spectra object gains a new slot
"processingChunkSize" that is used to define the size of the
processing chunks for the Spectra. See also issue #304. This ensures
processing also of very large data sets.
Changes in 1.13.1
- Fix issue with bin function (see issue #302). Addition of zero.rm
parameter to prevent creation of empty bins.
Changes in version 1.11
Changes in 1.11.11

#302). Thanks Adriano Rutz for reporting.
Changes in 1.11.10
- peaksData,MsBackendMemory returns a data.frame if additional peak
variables (in addition to "mz" and "intensity") are requested. For
columns = c("mz", "intensity") (the default) a list of matrix is
returned.
- peaksData,Spectra returns either a matrix or data.frame and ensures
the peak data is correctly subset based on the lazy evaluation
processing queue.
- $,Spectra to access peak variables ensures the lazy evaluation queue
is applied prior to extracting the values.
- applyProcessing correctly subsets and processes all peak variables
depending on the processing queue.
- spectraData<-,Spectra throws an error if processing queue is not
empty and values for peaks variables should be replaced.
- $<-,Spectra throws an error if processing queue is not empty and a
peaks variable is going to be replaced.
- Add full support for additional peaks variables to
MsBackendDataFrame.
Changes in 1.11.9

spectrum with m/z values relative to the precursor m/z of the

- Add an example to the vignette describing how spectral similarity
scores from the msentropy package can be used with compareSpectra.
Changes in 1.11.7

the peak similarity calculation functions FUN: this allows to use
custom similarity function with integrated mapping of peaks.
- Add joinPeaksNone to skip the peak matching in compareSpectra if the
similarity scoring function performs its own peak matching.
- Only use parallel processing in setBackend,Spectra if both backends
support it.
Changes in 1.11.6
- Add filterPrecursorMaxIntensity function.

first matching peak instead of all matching peaks (given ppm and
tolerance). Issue #274.
- Add parameter keep to filterMzRange to support keeping or removing
matching peaks.
Changes in 1.9.13
- Add the backendBpparam method that allows to evaluate whether a
