【问题描述】：
我使用过以前（与其他数据一起）工作的代码来可视化新数据。现在，我收到一条错误消息。由于代码正在处理其他数据，我想我的新数据与stat_contour() 不喜欢的方式有所不同。
我的这行代码产生了问题：
stat_contour(aes(z=log_llh),bins=15,colour='black',size=0.5) +
错误信息是：
轮廓线错误(x = sort(unique(data$x)), y = sort(unique(data$y)), : （列表）对象不能被强制输入'double' if (nrow(layer_data) == 0) return() 出错：参数长度为零
这是我的数据的 sn-p：
rec,foi,sensit,prev,log_llh,log_llh_prev,log_llh_decay,p_prev,p_decay,p_min

之前有人遇到过问题，问题是数据矩阵没有遵循规则网格。我的网格有 0.1 (rec) 和 0.01 (foi) 的常规增量。
有人知道可能出了什么问题吗？
PS：用geom_tile(aes(fill=log_llh)) 绘制完全相同的数据可以正常工作，而stat_contour(aes(z=log_llh),bins=15,colour='black',size=0.5) 仍然无法正常工作

您的 x 和 y 值使用什么？请给出可与上述示例数据一起使用的精确绘图命令，以产生您遇到的相同错误消息。某处应该有
ggplot或qplot命令。
