详情----------Details----------
The plot format is basically a scatter plot of the observed test statistics, overlayed with isolines showing the estimated fdr. The generic plot function displays the original test statistics that are used to estimate the fdr, i.e. the two-sample t-statistics and the logarithmized standard errors; the other plots use different, but mathematically equivalent test statistics:
图格式基本上是一个散点图，观测试验统计显示，估计FDR等值线叠加。通用的绘图功能显示原始测试是用来估计的FDR，即两样本t-统计量和标准误差logarithmized统计;其他使用不同的图，但数学上是等价的测试统计：
mean difference and logarithmized standard error for the tornado plot,
平均差和龙卷风图logarithmized标准错误，
mean difference and -\log10(p) for the volcano plot, where p is the p-value from the standard two-sample t-test.
平均差和-\log10(p)为火山图，其中p是从标准的两样本t检验的p值。
By default, the estimated fdr isolines are smoothed and cropped to the convex hull of the observed test statistics by using akima. This is entirely a graphical pre-processing step which produces smoother isolines and enforces sanity at the edges of the observed distribution; it does not change the estimated fdr at all. This graphical smoothing is controlled via the argument nr.plot, which specifies the grid size, with lower values resulting in stronger smoothing. In order to suppress graphical smoothing, set nr.plot to zero.
默认情况下，估计FDR等值线平滑和裁剪凸包的观测试验统计，使用akima。这完全是一个图形化的前处理步骤，产生平滑的等值线和强制执行的理智，在所观察到的分布的边缘，它不会改变估计FDR所有。这种图形的平滑控制通过参数nr.plot，指定网格的大小，数值较低，导致更强的平滑。为了抑制图形平滑，设置nr.plot为零。
Note that the test statistics and the fdr for the volcano- and tornado plots are not computed from scratch, but rather through transformation of the original results. Specifically, the isolines in these plots are also transformed; this has the unfortunate side effect that the labelling of isolines in these plots is not nearly as pretty as the standard provided by contour. This functionality is currently not available outside of contour, and our implementation in DrawContourlines frankly leaves a lot to be desired. We apologize for the inconvenience.
请注意，测试统计和火山和龙卷风图FDR不是从零开始，而是通过改造原有结果计算。具体来说，在这些图的等值线也转化;等值线在这些图的标签是不是几乎一样漂亮的标准contour，这个不幸的副作用。此功能目前是不外contour，我们实施DrawContourlines坦言留下了很多理想。给您带来不便，我们深表歉意。
