译者:生物统计家园网 机器人LoveR
描述----------Description----------
Plot selected ions in a given time range.
图选择在一个特定的时间范围内的离子。
用法----------Usage----------
plotPeak(rawpeaks, time.range, masses, cdfFile = NULL, useRI = FALSE,
rimTime = NULL, standard = NULL, massRange = c(85, 500), ...)
参数----------Arguments----------
参数:rawpeaks
A two component list containing the retention time and the intensity matrices. See peakCDFextraction.
一两个组件的列表,其中包含的保留时间和强度矩阵。看到peakCDFextraction。
参数:time.range
The time range to plot in retention time or retention time index units to plot.
保留时间或保留时间指标单位绘图绘制的时间范围。
参数:masses
A vector containing the ions or masses to plot.
一个矢量绘图含有离子或群众。
参数:cdfFile
The name of a CDF file. If a file name is specified, the ions will be extracted from there instead of using rawpeaks.
一个CDF文件的名称。如果指定一个文件名,将离子从那里提取,而不是使用rawpeaks。
参数:useRI
Logical. Whether to use Retention Time Indices or not.
逻辑。是否使用保留时间指数或不是。
参数:rimTime
A retention time matrix of the found retention time markers. It is only used when useRI is TRUE.
一个发现的保留时间标记的保留时间矩阵。它只是用来当useRI是TRUE。
参数:standard
A numeric vector with RI values of retention time markers. It is only used when useRI is TRUE.
与RI值的保留时间标记的数字向量。它只是用来当useRI是TRUE。
参数:massRange
A two component numeric vector with the scan mass range to extract.
两元件数值向量与扫描质量范围内提取。
参数:...
Further options passed to matplot.
进一步的选项,通过matplot。

require(TargetSearchData)
data(TargetSearchData)
# update CDF path[更新民防路径]
CDFpath(sampleDescription) <- file.path(.find.package("TargetSearchData"), "gc-ms-data")
# Plot the peak "Valine" for sample number 1[画出样本数1高峰“缬氨酸”]
grep("Valine", libName(refLibrary)) # answer: 3[答案:3]
# select the first file[选择第一个文件]
cdfFile <- CDFfiles(sampleDescription)[1]
# select "Valine" top masses[选择“缬氨酸”顶级群众]
top.masses <- topMass(refLibrary)[[3]]
# plot peak from the cdf file[CDF文件的积峰]
plotPeak(cdfFile = cdfFile, time.range = libRI(refLibrary)[3] + c(-2000,2000),
masses = top.masses, useRI = TRUE, rimTime = RImatrix[,1],
standard = rimStandard(rimLimits), massRange = c(85, 500))
# the same, but extracting the peaks into a list first. This may be better if[相同的,但提取到一个列表的第一峰。这可能是更好,如果]
# you intend to loop through several peaks.[你打算通过几个峰回路。]
rawpeaks <- peakCDFextraction(cdfFile, massRange = c(85,500))
plotPeak(rawpeaks, time.range = libRI(refLibrary)[3] + c(-2000,2000),
masses = top.masses, useRI = TRUE, rimTime = RImatrix[,1],
standard = rimStandard(rimLimits), massRange = c(85, 500))
