描述----------Description----------
A NoiseModel represent the technical variation which is dependent on signal intensity.
一个NoiseModel代表的技术变化,这是依赖于信号强度。
构造----------Constructor----------
Creates a new NoiseModel object based on ibspectra object.
创建一个新的NoiseModel基于ibspectra对象的对象。
type: A non-virtual class deriving from NoiseModel: ExponentialNoiseModel, ExponentialNoANoiseModel,
type:非虚拟类派生从NoiseModel:ExponentialNoiseModel,ExponentialNoANoiseModel
reporterTagNames: When NULL, all channels from ibspectra are taken (i.e. sampleNames(ibspectra)). Otherwise, specify
reporterTagNames“:当空,采取从ibspectra所有通道(即sampleNames(ibspectra))。否则,请指定
one.to.one: Set to false to learn noise model one a non
one.to.one:设置为false,了解噪声模型的一个非
min.spectra: When one.to.one=FALSE, only take proteins
min.spectra:当one.to.one = FALSE时,只需要蛋白质
plot: Set to true to plot data the noise model is learnt on.
plot:设置为true,地积噪声模型上了解到的数据。
pool: If false, a NoiseModel is estimated on each combination of channels indivdually, and then the parameters are averaged. If true,
pool:如果为false,NoiseModel估计每个渠道indivdually组合,然后参数的平均值。如果情况属实,
存取方法----------Accessor methods----------
noiseFunction: Gets the noise function.
noiseFunction:获取噪音的功能。
parameter: Gets and sets the parameters for the noise function.
parameter:获取和设置的噪声函数的参数。
variance: Gets the variance for data points based on
variance:获取数据点的基础上变异
stddev: Convenience function, sqrt(variance(...)).
stddev:方便的功能,sqrt(variance(...))。
lowIntensity: Gets and sets the low intensity slot, denoting the noise region.
lowIntensity:获取和设置强度低槽,表示噪声区域。
naRegion: Gets and sets the na.region slot.
naRegion:获取和设置na.region插槽。
举例----------Examples----------
data(ibspiked_set1)
ceru.proteins <- protein.g(proteinGroup(ibspiked_set1),"CERU")
# normalize[标准化]
ibspiked_set1 <- normalize(correctIsotopeImpurities(ibspiked_set1))
# remove spiked proteins[去除尖刺的蛋白质]
ibspiked_set1.noceru <- exclude(ibspiked_set1,ceru.proteins)
ibspiked_set1.justceru <- subsetIBSpectra(ibspiked_set1,protein=ceru.proteins,direction="include")
# learn noise models[学习的噪声模型]
nm.i <- new("InverseNoiseModel",ibspiked_set1.noceru)
nm.e <- new("ExponentialNoiseModel",ibspiked_set1.noceru)
#learn on non-one.to.one data: not normalized, with spiked proteins[学习非one.to.one数据:不归,钉蛋白质]
nm.n <- new("ExponentialNoiseModel",ibspiked_set1.justceru,one.to.one=FALSE)
maplot(ibspiked_set1,noise.model=c(nm.e,nm.i,nm.n),ylim=c(0.1,10))
