我正在尝试使用 R 绘制 csv 数据的 3d 曲面图，但我不知道我将如何做到这一点。csv 文件 ( sphere.csv) 是

我能够像这样阅读它
sphere_data <- read.csv (file="sphere.csv", head=FALSE, sep=",")
然后我尝试使用wireframe：
library(lattice)
wireframe(z~x+y,sphere_data)
但这给了我一个错误。特别是，口译员似乎对z表达的内容感到窒息z~x+y。我不知道那个表达是什么意思，但我在互联网上的其他例子中找到了它。

根据shujaa的建议，dput(sphere_data)返回

csv 中的数据有 11x11 个值。这些值应该表示一个点的高度（比如 z 轴）。csv 中第一行的所有值都在同一个 x 轴上，第二行的值也是如此，直到最后一行的值。每行的第一个值在相同的 y 轴上，对于每行的第二个值也是如此，直到最后一行的值。
