1.63.6版更改(2022-10-15)-修复了cwt()中尺度长度为1时的回归问题。1.63.5版更改- getRidge()支持scaleToWinSize形参此参数控制缩放如何映射到窗口大小。这些窗口用于跟踪本地极大值到脊。MassSpecWavelet的标准是winsize <- 2*scale+1, xcms修改为winsize <- floor(scale/2)。这个新参数允许xcms维护者使用他们的标准调用MassSpecWavelet的getRidge(如果他们愿意的话)，同时它仍然允许我们在结果中保持向后兼容性。参见?getRidge了解更多细节。- getLocalMaximumCWT()的is_amp_thres_relative参数现在是isAmpThreshRelative，与包中的其他参数大写一致。由于它是10天前推出的，我认为不会有超过一个用户使用它。- getLocalMaximumCWT()和peakDetectionCWT有一个exclude0scaleAmpThresh参数。 When computing the relative amp.Th, if this parameter is set to TRUE, the amp.Th will exclude the zero-th scale from the max(wCoefs). The zero-th scale corresponds to the original signal, that may have a much larger baseline than the wavelet coefficients and can distort the threshold calculation. The default value is FALSE to preserve backwards compatibility. - peakDetectionCWT lets the user pass custom arguments to getRidge(). Changes in version 1.63.4 (2022-10-10) - The improvements in localMaxima() and cwt() provide significant speed-ups to peakDetectionCWT() as well as better scalability. - A prepareWavelets() function lets the user pre-compute the daughter wavelets for more efficient cwt() calculations when applied on multiple spectra. When used transforming 1000 spectra, of 2000 points long each, using 25 different scales, cwt() is twice as fast as in previous versions. Further improvements to avoid some memory allocations are still feasible in future versions. - Through the prepareWavelets() function, we provide the extendLengthScales argument, that provides the same functionality than the extendLengthMSW argument in xcms:::MSW.cwt(). - The peakDetectionCWT() function accepts a prepared_wavelets object in the scales argument for better efficiency. Changes in version 1.63.3 (2022-10-10) - localMaxima() has a more efficient implementation of the algorithm, now being 10x faster than before, while giving the same results. - Experimentally, localMaxima() can use a new and different algorithm for detecting local maxima. See the new "Finding local maxima" vignette for further details. Changes in version 1.63.2 (2022-09-29) - Let getLocalMaximumCWT() have a relative amp.Th. Related to #4. - Fix bug on identifyMajorPeaks() where nearbyWinSize was forced to 150 if nearbyPeak was set to TRUE. Related to #4. - Added excludeBoundariesSize argument to identifyMajorPeaks(). Before, nearbyWinSize was used for two different but related criteria: the range for including peaks close to a large peak AND the range to exclude peaks close to the beginning and end of the signal. Now, we have two independent arguments for each setting. The current behaviour does not change, but it is now more flexible. Related to #4. Changes in version 1.63.1 (2022-07-08) - Drop sav.gol alias from the documentation. Related to #2 - Explain how the scales argument is defined in relation to the mother wavelet. - Add sessionInfo() to the vignette Changes in version 1.61.3 (2022-04-05) - Add signal to Suggests. Replace sav.gol() with signal::sgolayfilt(). Closes #2 - Minor documentation improvements Changes in version 1.61.2 (2022-04-04) - Remove xcms and caTools. Those are great packages but we don't use them directly in MassSpecWavelet. - Replace Sweave with RMarkdown vignette and update styles with BiocStyle Changes in version 1.61.1 (2022-04-01) - Change Maintainer to Sergio Oller - Add NEWS.md file - Fix warning (error on R>=4.2) when cwt() has a matrix in the wavelet argument - Fix warning due to partial matching of arguments inside cwt() - Move waveslim from Depends to Suggests - Make all calls to recommended packages qualified (e.g. sd -> stats::sd) - Remove empty sections in man/ files. - Register C routines
