描述----------Description----------
Group peaks together across samples using overlapping m/z bins and calculation of smoothed peak distributions in chromatographic time.
集团高峰跨样品的色谱重叠的m / z箱和平滑的峰值分布计算。
参数----------Arguments----------
参数：object
the xcmsSet object
xcmsSet对象
参数：minfrac
minimum fraction of samples necessary in at least one of the sample groups for it to be a valid group
样品必要的最低分数至少在它的样本群体之一，是一个有效的组
参数：minsamp
minimum number of samples necessary in at least one of the sample groups for it to be a valid group
最低所需样品数量至少在它的样本群体之一，是一个有效的组
参数：bw
bandwidth (standard deviation or half width at half maximum) of gaussian smoothing kernel to apply to the peak density chromatogram
带宽高斯平滑核心（标准偏差或半高半宽）适用于峰值电流密度色谱
参数：mzwid
width of overlapping m/z slices to use for creating peak density chromatograms and grouping peaks across samples
重叠的m / z片用于创建峰值密度色谱和分组各样品的峰宽
参数：max
maximum number of groups to identify in a single m/z slice
最大的群体数量，以确定在一个单一的m / z片
参数：sleep
seconds to pause between plotting successive steps of the peak grouping algorithm. peaks are plotted as points showing relative intensity. identified groups are flanked by dotted vertical lines.
秒暂停之间绘制的高峰期分组算法的连续步骤。峰绘制点，呈现出相对强度。鉴定组虚线垂直线两侧。
值----------Value----------
An xcmsSet object with peak group assignments and statistics.
