groupval-methods()所属R语言包:xcms
Extract a matrix of peak values for each group
各组提取的高峰值矩阵
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Generate a matrix of peak values with rows for every group and columns for every sample. The value included in the matrix can be any of the columns from the xcmsSet peaks slot matrix. Collisions where more than one peak from a single sample are in the same group get resolved with one of several user-selectable methods.
生成每个样品各组和列行的高峰值的矩阵。矩阵中包含的值可以是任何列的从xcmsSetpeaks插槽矩阵。多个从单个样品的高峰期是在同一组的碰撞得到解决的几个用户可选择的方法之一。
参数----------Arguments----------
参数:object
the xcmsSet object
xcmsSet对象
参数:method
conflict resolution method, "medret" to use the peak closest to the median retention time or "maxint" to use the peak with the highest intensity
解决冲突的方法,"medret"使用最接近中位数的保留时间或"maxint"使用强度最高的高峰,高峰
参数:value
name of peak column to enter into returned matrix, or "index" for index to the corresponding row in the peaks slot matrix
峰列的名称,进入返回矩阵,或"index"peaks插槽矩阵对应的行指数
参数:intensity
if method == "maxint", name of peak column to use for intensity
如果method == "maxint",高峰列的名称,使用强度
值----------Value----------
A matrix with with rows for every group and columns for every sample. Missing peaks have NA values.
与每个样品各组和列的行矩阵。失踪的山峰有NA值。
方法----------Methods----------
groupval(object, method = c("medret", "maxint"), value = "index", intensity = "into")
groupval(object, method = c("medret", "maxint"), value = "index", intensity = "into")
