R ggplot2统计轮廓：错误消息不清楚

我使用了以前使用过的代码（与其他数据一起）来可视化新数据。现在，我收到一条错误消息。由于代码使用的是其他数据，因此我认为我的新数据在某种程度上不同于

stat\u contour（）

所不喜欢的

我的这行代码产生了以下问题：

stat_contour(aes(z=log_llh),bins=15,colour='black',size=0.5) +

错误消息是：

轮廓线错误（x=排序（唯一（数据$x）），y=排序（唯一（数据$y）），： （列表）对象不能强制为“double”类型 if（nrow（layer_data）==0）return（）中出错：参数的长度为零

以下是我的数据片段：

以前有人遇到过这个问题，问题是数据矩阵没有遵循规则网格。我的网格有规则增量0.1（rec）和0.01（foi）

有人知道什么地方出了问题吗

注：使用

geom_tile（aes（fill=log_llh））

绘制完全相同的数据效果非常好，而

stat_court（aes（z=log_llh），bins=15，color='black'，size=0.5）

仍然不起作用

谷歌搜索发现： 他们说：

不管是什么导致了这个错误，它都不能告诉我们在哪里 这个 真正的问题在于

原来问题是“stat_contour”函数 期望在（x，y）值的规则网格上查找数据，以及我们的数据 根本不在任何网格上

---

因此，您可能需要确保您的

x

和

y

是网格。

您对x和y值使用的是什么？请给出一个精确的绘图命令，该命令可以与上述示例数据一起使用，以生成与您遇到的错误消息相同的错误消息。应该在某处有

ggplot

或

qplot

命令。
