无法在R中绘制温度数据的等高线

我的数据以给定格式保存在csv文件中

csv文件数据 我尝试使用

contour（）

，

contourplot（）

等绘制轮廓，我不知道如何使数据规则化以获得轮廓。我尝试了akima

interp（）

，但得到了下面给出的错误。不知道这意味着什么，也不知道如何修正数据以获得轮廓

*is.finite（x）中的错误：未为类型“list”实现默认方法*

有人请帮帮我。谢谢。

这对我来说很有效（顺便说一句，转储这个大小的数据文件，即使它只是中等大小，对响应者来说也是一种痛苦：如果你能把它发布到更容易的地方。我必须保存HTML页面源代码并以这种方式提取信息，因为它太大了，我无法从剪贴板上剪切和粘贴）：
