描述----------Description----------
Based on the identified peak position, more precise estimation of the peak information, i.e., peak position and peak scale, can be got by this function. The basic idea is to cut the segment of spectrum near the identified peaks, and then do similar procedures as peakDetectionCWT, but with more detailed scales around the estimated peak scale.
基于峰值位置的确定,更精确的估计高峰期的信息,即,峰值位置和峰值规模,可以得到这个功能。其基本思路是减少确定峰附近的频谱段,然后做类似的程序peakDetectionCWT,但与周围的估计高峰期的规模更详细的尺度。

data(exampleMS)
SNR.Th <- 3
peakInfo <- peakDetectionCWT(exampleMS, SNR.Th=SNR.Th)
majorPeakInfo <- peakInfo$majorPeakInfo
betterPeakInfo <- tuneInPeakInfo(exampleMS, majorPeakInfo)
plot(500:length(exampleMS), exampleMS[500:length(exampleMS)], type='l', log='x')
abline(v=betterPeakInfo$peakCenterIndex, col='red')
