retcor.peakgroups-methods(xcms)
retcor.peakgroups-methods()所属R语言包:xcms
Align retention times across samples
对齐跨样品的保留时间
译者:生物统计家园网 机器人LoveR
描述----------Description----------
These two methods use “well behaved” peak groups to calculate retention time deviations for every time point of each sample. Use smoothed deviations to align retention times.
这两种方法使用“表现良好”峰组来计算每个样本的每一个时间点的滞留时间偏差。使用平滑偏差调整保留时间。
参数----------Arguments----------
参数:object
the xcmsSet object
xcmsSet对象
参数:missing
number of missing samples to allow in retention time correction groups
失踪样品的数量,使保留时间校正组
参数:extra
number of extra peaks to allow in retention time correction correction groups
额外峰的数量,使保留时间校正校正组
参数:smooth
either "loess" for non-linear alignment or "linear" for linear alignment
无论是非线性"loess"对齐或"linear"线性对齐
参数:span
degree of smoothing for local polynomial regression fitting
局部多项式回归拟合平滑度
参数:family
if gaussian fitting is by least-squares with no outlier removal, and if symmetric a re-descending M estimator is used with Tukey's biweight function, allowing outlier removal
如果gaussian装修是没有离群去除最小二乘,如果symmetric重新降的M估计用于Tukey的biweight功能,使去除离群
参数:plottype
if deviation plot retention time deviation points and regression fit, and if mdevden also plot peak overall peak density and retention time correction peak density
如果deviation图的保留时间偏差点和回归拟合,如果mdevden还绘制高峰的整体峰值密度和保留时间校正峰值电流密度
参数:col
vector of colors for plotting each sample
向量绘图每个样品的颜色
参数:ty
vector of line and point types for plotting each sample
线和点类型的矢量绘制每个样品
值----------Value----------
An xcmsSet object
