getEIC-methods(xcms)
getEIC-methods()所属R语言包:xcms
Get extracted ion chromatograms for specified m/z ranges
提取指定的m / z范围的离子色谱
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Generate multiple extracted ion chromatograms for m/z values of interest. For xcmsSet objects, reread original raw data and apply precomputed retention time correction, if applicable.
生成多个感兴趣的m / z值提取离子色谱图。 xcmsSet对象,重读原始数据,并适用于预先计算的保留时间校正,如适用。
参数----------Arguments----------
参数:object
the xcmsRaw or xcmsSet object
xcmsRaw或xcmsSet对象
参数:mzrange
either a two column matrix with minimum or maximum m/z or a matrix of any dimensions containing columns mzmin and mzmax for xcmsSet objects, if left blank the group data will be used instead
无论是两个最大或最小的m / z或载列的任何尺寸的矩阵列的矩阵mzmin和mzmaxxcmsSet对象,如果留空组的数据将被用来代替
参数:rtrange
a two column matrix the same size as mzrange with minimum and maximum retention times between which to return EIC data points for xcmsSet objects, it may also be a single number specifying the time window around the peak to return EIC data points
一个两列的矩阵大小相同mzrange之间返回xcmsSet对象为三电数据点的最低和最高的保留时间,它也可能是单数指定的时间窗口,绕峰回三电数据点
参数:step
step size to use for profile generation
步长,使用个人资料的代
参数:groupidx
either character vector with names or integer vector with indicies of peak groups for which to get EICs
无论名称或峰组的序号为整数向量的特征向量得到EICs
参数:sampleidx
either character vector with names or integer vector with indicies of samples for which to get EICs
无论是与序号为为得到EICs的的样品名称或整数向量的特征向量
参数:rt
"corrected" for using corrected retention times, or "raw" for using raw retention times
"corrected"使用原始的保留时间校正保留时间,或"raw"使用
值----------Value----------
For xcmsRaw objects, if rtrange is NULL, an intensity matrix with a row for each mzmin, mzmax pair. Columns correspond to individual scans. If rtrange is not NULL, a list of two column (retention time/intensity) matricies, one for each mzmin, mzmax pair.
xcmsRaw对象,如果rtrange是空的,每个mzmin,mzmax对连续的强度矩阵。列对应个别扫描。如果“rtrange是不是NULL,两列(保留时间/强度)基质中,一个每个mzmin,mzmax对的列表。
For xcmsSet objects, an xcmsEIC object.
xcmsSet对象,xcmsEIC对象。
方法----------Methods----------
getEIC(object, mzrange, rtrange = NULL, step = 0.1)
getEIC(object, mzrange, rtrange = NULL, step = 0.1)
getEIC(object, mzrange, rtrange = 200, groupidx, sampleidx = sampnames(object), rt = c("corrected", "raw"))
getEIC(object, mzrange, rtrange = 200, groupidx, sampleidx = sampnames(object), rt = c("corrected", "raw"))
