R levelplot和插值[关闭]答案

【问题标题】：R levelplot and interpolation [closed]R levelplot和插值[关闭]
【发布时间】：2012-11-06 12:34:56
【问题描述】：

几天前，我设法在脚本中使用以下命令制作了带有插值的水平图：

levelplot(jan~lon*lat,APM,main="Jan",panel=panel.levelplot.raster,interpolate=T)

我不小心没有保留那个会话，只保留了脚本，所以我无法浏览历史并恢复我使用过的所有命令。

现在，在加载 latticeExtra 之后，相同的命令会生成一个空图。另一方面，省略指令的最后两个元素，即：

levelplot(jan~lon*lat,APM,main="Jan")

图表已绘制。

我想在表面进行插值，但是出了点问题

panel=panel.levelplot.raster

加载 rasterVis 时会发生相同的行为。我想我错过了什么……有什么帮助吗？

数据结构如下：

【问题讨论】：

不可重现情节的可重现示例可能会有所帮助！
您好，感谢您的关注。刚刚用一个关于数据实际结构的例子更新了这个问题。希望对您有所帮助。
在数据的 sn-p 中，lon 没有变化。这使得不可重现性可重现（产生警告并且绘图窗口中没有任何内容）并且可能是您的问题的原因。如果您的完整数据集中lon 存在差异，请考虑将head(APM) 的结果替换为dput(APM) 的结果。
该情节适用于 lat、lon 和 jan 的前 152 个条目，可以从您发布的内容中获得（dput 已被切断...）。再次，请发布一个可重现的问题示例。
再次感谢您的关注。我不认为数据本身有问题，因为在没有插值的情况下绘制 jan 与 lat 和 lon 的水平图就可以了。

标签： r lattice levelplot

【解决方案1】：

以下在 R 的新交互式会话中生成一个情节

APM <- results of dput(APM) from the OP

library(latticeExtra)

levelplot(jan~lon*lat,APM,main="Jan",panel=panel.levelplot.raster,interpolate=T)

或者

levelplot(jan~lon*lat,APM,main="Jan",interpolate=TRUE, useRaster = TRUE)

如果这不适合您，请检查您是否拥有相关软件包的最新版本；例如，

R version 2.15.2 (2012-10-26)
latticeExtra_0.6-24
lattice_0.20-10
RColorBrewer_1.0-5

如果问题仍然没有解决，还有其他的东西没有在这篇文章中提到。

【讨论】：

只需更新软件包即可解决。非常感谢您的宝贵时间。
@AlexCaseiro，酷！很高兴它成功了。
