描述----------Description----------

This is a class to represent a set of samples.
这是一个类来表示一组样品。


类的对象----------Objects from the Class----------

Objects can be created by the function ImportSamples or by calling the object generator function.
对象可以创建功能ImportSamples或通过调用对象发生器功能。

new("tsSample", Names = [sample names], CDFfiles = [list of CDF file names],      RIfiles = [list of RI file names], CDFpath = [CDF files path],                  RIpath = [RI files path], days = [measurement days],                  data = [additional sample information])
new("tsSample", Names = [sample names], CDFfiles = [list of CDF file names],      RIfiles = [list of RI file names], CDFpath = [CDF files path],                  RIpath = [RI files path], days = [measurement days],                  data = [additional sample information])


插槽----------Slots----------




Names: "character", the sample names.
Names："character"，样品名称。




CDFfiles: "character", the list of CDF file names.
CDFfiles："character"，CDF文件名列表。




RIfiles: "character", the list of RI file names.
RIfiles："character"，RI文件名列表。




CDFpath: "character", CDF files path.
CDFpath："character"，CDF文件的路径。




RIpath: "character", RI file path.

举例----------Examples----------


showClass("tsSample")

# get a list of CDF files from a directory[CDF文件从一个目录列表]
require(TargetSearchData)
CDFpath <- system.file("gc-ms-data", package = "TargetSearchData")
cdffiles <- dir(CDFpath, "cdf")

# define the RI file path [定义RI文件路径]
RIpath  <- "."

# create the sample object[创建样本对象]
sampleDescription <- new("tsSample", CDFfiles = cdffiles, CDFpath = CDFpath, RIpath = RIpath)

##[＃]

# More parameters could be defined:[可以定义多个参数：]
# define the RI files and the RI path[定义RI文件和RI路径]
RIfiles <- sub("cdf$", "txt", paste("RI_", cdffiles, sep = ""))
RIpath  <- "."

# get the measurement days (the four first numbers of the cdf files, in this[测量天（CDF文件，在这四个第一的数字，]
# example)[例如）]
days <- substring(cdffiles, 1, 4)

# sample names [样品名称]
smp_names <- sub(".cdf", "", cdffiles, fixed = TRUE)

# add some sample info[添加一些样品信息]
smp_data <- data.frame(CDF_FILE =cdffiles, GROUP = gl(5,3))

# create the sample object[创建样本对象]
sampleDescription <- new("tsSample", Names = smp_names, CDFfiles = cdffiles, CDFpath = CDFpath,
    RIpath = RIpath, days = days, RIfiles = RIfiles, data = smp_data)

# changing the sample names[改变样品名称]
sampleNames(sampleDescription) <- paste("Sample", 1:length(sampleDescription), sep = "_")

# changing the file paths (relative to the working path)[改变文件路径（相对工作路径）]
CDFpath(sampleDescription) <- "my_cdfs/"
RIpath(sampleDescription)  <- "my_RIs/"
