方法----------Methods----------
show signature(object="rowROC") Print nice info
显示signature(object="rowROC")打印好的信息
[ signature(x="rowROC", j="missing") Subset the
[signature(x="rowROC", j="missing")子集
plot signature(x="rowROC", y="missing") Plot the ROC curve of the first row of the object along with the pAUC. To plot the curve for a specific row/gene subsetting should be done
图signature(x="rowROC", y="missing")绘制对象沿着与pAUC的第一行的ROC曲线。要绘制一个特定的行/基因子集的曲线应做
pAUC signature(object="rowROC", p="numeric", flip="logical") Integrate area under the curve from 0 to p. This method
