discretize.tscores(macat)
discretize.tscores()所属R语言包:macat
Discretize regularized t-scores
离散化正规化的T-分数
译者:生物统计家园网 机器人LoveR
描述----------Description----------
discretize.tscores returns a discretized version of the scores in the MACATevalScoring object. Discretization is performed by comparing the value gene-wise (location-wise) with the symmetric upper and lower quantile given by margin (in percent margin/2 lower and upper quantile). discretizeAllClasses produces a flatfile readable by PYTHON.
discretize.tscores返回分数在MACATevalScoring对象的离散版本。离散化是由对称的上下缘定的位数(百分比保证金/ 2上下位数)比较明智的基因(位置上)的价值。 discretizeAllClasses产生1平面文件由Python可读。
用法----------Usage----------
discretize.tscores(scores)
discretizeAllClasses.tscores(data, chrom, nperms=10, kernel=rbf, kernelparams=NULL, step.width=100000)
参数----------Arguments----------
参数:scores
a MACATevalScoring object obtained from evalScoring

参数:data
a MACATData Object containing all expression values, geneLocations and labels (obtained from preprocessedLoader)
1 MACATData对象包含所有表达式的值,geneLocations和标签(从preprocessedLoader的取得)
参数:chrom
chromosome that is discretized
离散的染色体
参数:nperms
number of permutations for the computation of empirical p values (evalScoring)
排列数计算经验P值(evalScoring)
参数:kernel
kernel function used for smoothing one of rbf, kNN, basePairDistance or your own
用于平滑的RBF之一,KNN,basePairDistance或自己的核心功能
参数:kernelparams
list of parameters for the kernels
为内核的参数列表
参数:step.width
size of a interpolation step in basepairs
在碱基插步的大小
Details
详情----------Details----------
The filename for the python flat files are discrete_chrom_<chrom>_class_<label>.py where <chrom> and <label> are the names of the chromosome and class label.
蟒蛇平面文件的文件名是discrete_chrom_<chrom>_class_<label>.py<chrom>和<label>染色体的名称和类的标签。

#loaddatapkg("stjudem")[loaddatapkg(“stjudem”)]
#data(stjude)[数据(stjude)]
data(stjd)
# simple scoring with short running time[运行时间短,简单的评分]
scores = evalScoring(stjd, "T", 1, nperms=100, cross.validate=FALSE)
